How to check the perforator button for serviceability. Replacement of the cartridge

How to remove the transpower switch

If your tool has become worse, or completely stopped performing its direct duties, it is time to diagnose the malfunctions and try to cope with them. First, check the wire for damage and the voltage in the outlet, for which you can include any other device. TV or kettle.

If you inspect the devices operating from the battery, they need to be checked when using a tester. in this case, the voltage indicated on the case must have a similar value with the battery voltage.

If the voltage is smaller, you will have to change the batteries to new. If the battery works normally, power supply is normal, look for problems in the hardware. The most common breakdowns are considered:

Knowing how the electric drill button is connected, you can quickly solve the malfunction. In addition, the problem with the work of the drill can occur due to the dustiness of the tool, because the drill “takes” the tree, and brick, and other materials. So, you should take care of cleaning the device after each use. the only way to reduce the risk of failures in work due to the contamination of the tool. That is why after you carried out repairs in the apartment, immediately clean the drill.

Drill repair: possible malfunctions

The drill is one of the demanded power tools that are popular not only during construction and finishing work. Depending on the nature of the operation of the tool and its quality, such negative consequences as breakdown of the drill may occur. To correct the situation, there is no need to buy a new tool, since you can repair the drill yourself.

What you need to know for this, as well as what breakdowns can occur on a drill, we will find out later.

Design features

The electric drill is a plastic case (sometimes metal), as well as the working area, presented in the form of a cartridge to fix the appropriate nozzles to perform various works. In the housing, the electroderlies are both electrical and mechanical parts.

The device of the electric part includes the following components:

AC electric motor two.phase.
Contact brushes located in the brush holder.
Power tool start button.
Power cable.
Revolution regulator.
The mechanism of switching the direction of rotation of the cartridge.
Start capacitor.

The device of the mechanical part is presented in the form of a gearbox and a system of bearings. Reducer function (set of gears) is to transmit torque from the electric motor shaft to the tool cartridge.

In shock drones and peorators, the mechanical part is additionally represented by two pistons, as well as a ram and a boy. These elements allow you to turn on the shock mode, that is, the function of the chipping hammer. The design of the tool is not at all complicated, therefore, even an inexperienced specialist will be able to eliminate arising breakdowns.

Before proceeding to eliminate the breakdown, the cause should be detected, and for this it is necessary to disassemble the tool.

Necessary tools and materials

To repair the drill with your own hands, you will need to use the following tools:

screwdrivers to disassemble the tool;
multimeter, to determine the malfunctions in the electrical part;
sandpaper to clean the oxidized contacts.

Depending on the causes of the breakdown, some materials will also require. These include:

In addition, if the tool has not understood for a long time, then it is advisable to change the lubricant in the gearbox during disassembly at the same time. This will reduce the load on the electric motor, and also allow you to extend the life of the tool. Bearings also need lubrication, therefore, regardless of the causes of the tool malfunction, after their elimination it is necessary to devote time to diagnostics.

Mechanical malfunctions

DIY drill repair begins with determining the causes of the tool malfunction. First you need to identify which part of the tool failed: electrical or mechanical. As a rule, this is not difficult to do this. The main problems of the mechanical part include:

Malfunctions of the mechanics are determined quite easily, since the sound of a working electric motor will be heard. If a gearbox or bearing is not serviceable, a characteristic sound will arise. If the cartridge is faulty, then the master will not be able to squeeze the working element in it.

Bearing bearings. Bearings can fail only if dust falls into the lubricant, or from exorbitant loads. If the bearing does not crumble, then it will not be difficult to eliminate the breakdown. To do this, disassemble the tool, rinse the bearing with kerosene, and then fill it with lubricants. After that, do not forget to replace the oil seals, since, most likely, it was because of them that the dust got inside the tool. It is better to lubricate bearings with special lubricants for high.speed devices.
Problems in the gearbox are eliminated only by replacing the gear. As a rule, a whole mechanism is replaced, since it is almost unrealistic to find any spare part separately. You can purchase a gearbox for a drill if your drill has a known name. If a drill of unknown or Chinese production, then any of the spare parts is almost unrealistic to find on it.
Bench of the cartridge. If a key cartridge is installed on the tool, then such products fail very rarely. But if this happens, then you need to replace the device in its entirety. In some cases, one sponge can jam in the cartridge, therefore, to eliminate the malfunction, the product must be disassembled and cleaned. Quickly packed cartridges fail more often, so they should be replaced with a new one after a breakdown or when the clamp is weakened.

Often, bearings or a reducer system, less often a cartridge, come out in the mechanical part. To eliminate the malfunction of the cartridge, there is no need to disassemble the tool. In any case, it is much cheaper to repair the mechanics of the drill than to resort to the acquisition of a new tool.

The most common electrical malfunctions

Electricity malfunctions are determined quite simply, since when you press the Start button, the tool will not publish characteristic signs of life. To repair the drill with breakdowns in the electric part, it is necessary to initially find the specific cause of the breakdown. Frequent malfunctions of the electrical part include:

Network wire malfunction. Few people give attention to this, but in the process of frequent operation of the drill, contact may simply be violated inside the network wire. To determine the malfunction, you will need to use the tester in the call mode. In this case, the tool fork should be removed from the outlet. If the malfunction is confirmed, then you should replace the cord or cut off the part on which there is an alleged violation of contact.
Damage to the button. If the network wire is working, then the reason must be sought in the button. This is especially true if the drills buttons have a built.in speed controller. The button node with the regulator is often clogged with dust and chips, so the contact may simply be violated. This knot can be disassembled and cleaned and blowing. If after this the drill is not launched, then you need to check the integrity of the contacts. In case of violation of the integrity of the contact, replace the button or button block with a new.
Washing the brush node. Through the brushes, the power supply is supplied to the engine rotor. During the operation of the electric motor, the brushes are gradually erased, so it is possible that with frequent use of the drill at one point, it will refuse to start. It will not be difficult to determine such a breakdown, and the replacement of the brushes is even easier.
Rotor malfunction. If the brushes are replaced, but the drill refuses to function, then the rotor integrity should be checked. The presence of scale and pollution on the collector should be removed using sandpaper. Using the multimeter in the mode of resistance measurement mode, you should check this value between the neighboring departments of the collector. The resistance value should be the same. If everything is in order, then you need to check the windings of the electric motor for the possibility of a short circuit. When detecting malfunctions, it is possible to rewind the winding, for which the rotor or stator must be handed over to the profile service.

Possible tool malfunctions. we carry out repairs ourselves

If your tool has become worse, or completely stopped performing its direct duties, it is time to diagnose the malfunctions and try to cope with them. First, check the wire for damage and the voltage in the outlet, for which you can include any other device. TV or kettle.

If you inspect the devices operating from the battery, they need to be checked when using a tester. in this case, the voltage indicated on the case must have a similar value with the battery voltage.

How to disassemble the button of the penetrator, if it broke. a renovation review

A professional construction tool always works in extreme conditions, therefore, both the mechanical and electrical part of the peorator has an increased working resource. As practice shows, a tool from brands such as Makita, Bosch or Interskol rarely fails during the warranty period, but sooner or later everything breaks down.

One of the most vulnerable places of any pedorator is the inclusion button with the rotation frequency regulator and the reverse switch.

Three types of button can be distinguished:

How to check the launch button of the penetrator?

To do this, you can use an electric multimeter (tester): you need to join the ends of the peorator fork and press the start button.

If the multimeter is the presence of resistance, then the circuit of the power tool. Lack of resistance indicates a violation of the integrity of the chain.

At the same time, you need to understand that the problem can be not only in the switch button. You should also check the electric cable for the presence of fractures, the degree of wear of coal brushes and the contacts of the reverse.

This is the only way to make sure that the reason lies precisely in the switch.

How to connect a drill button yourself?

Despite the fact that this process is quite complicated, you can do all your work with your own hands, observing some important rules. For example, remember that the opening of the case can lead to the fact that all parts and poorly fixed spare parts will simply fall out of the case. Naturally, this should be avoided, because then it will be quite difficult to assemble the device together. To do this, you can smoothly raise the lid, noting the exact location of the spare parts on paper.

The button is repaired as follows:

First, locks for the casing are tidied, after which it is carefully pulled out;
All rusted and darkened terminals are cleaned of soot, for which you can use alcohol or sandpaper;
We re.collect the tool, making sure that all the details of the device are in its place, and check the operability of the drill. if nothing changes, we change the detail;
We fill the circulation regulator with a compound, and therefore, when failing, the part is simply replaced by the part;
Frequent breakdown is the erasure of the working layer under the rheostat. it is better not to repair it, just spend time in vain, it is better to purchase a new one and replace it and replace it.

Many are interested in where to get a similar scheme? First of all, she should go along with the instrument when buying it, but if there is no scheme, or you lost it, you will have to look on the Internet. After all, only with its help you can carry out repairs correctly, without errors. By the way, the speed control button and the reverse control button are located in different places, and therefore they will have to be checked separately.

Electric motor verification: causes of breakdowns and repair

There are several reasons for the breakdowns of an armature or stator drill. First of all, it is illiterate operation of the device. For example, many users simply overload the tool, working without a break. This leads to the fact that the drill engine does not have time to “relax”. The second reason lies in a bad motor wire, which are often found in cheap models. That is why the breakdowns of cheap tools are much more common. Repair in this case must be carried out using a specialized tool. And it will be better if you entrust this work to professional specialists.

But the drill may not work due to banal malfunctions-for example, due to brushes inside the engine. So, you can’t do without repairing brushes here, while this work is quite simple. you do not even need to have special knowledge and tools. To do this, analyze the device, remove the brush holders from it and change the details that are broken. By the way, there are models whose body can not be disassembled. you just need to remove special plugs through the installation window, after which we change the brushes.

You can purchase these details in any construction store, there are also some models that are sold together with a set of additional brushes. It is important that you do not wait for the complete wear of the brushes. check them from time to time. And all due to the fact that the risk of the formation of a gap between the bristles and the collector arises. As a result, this detail will begin to overheat and disappears over time. it means that you will have to change the whole anchor, which will be much more expensive and more complicated, and not the fact that you can independently solve this issue.

As you can see, there are a variety of breakdowns, many of which will be subject to you, others will be feasible only to specialists in service centers. And to reduce the risk of such breakdowns, you need to take care of your tool, clean it after work, check the condition of parts and brushes in order to replace them with new. However, if you see that you yourself will not be able to cope. bring the device to the workshop.

For drilling holes in various materials, breaking walls, drilling of rocks and roads, a peorator is intended. The tool is used for large loads and over time it has malfunctions. You can replace the failed peorator with an inexpensive Chinese model. But if you have a branded tool, then it’s a pity to throw it out. In order not to give half the cost of the penetrator for eliminating malfunctions, you can do it yourself. No repair is complete without studying the device of the tool and the procedure for disassembling it.

In modern electric manual droplets, the launch button is responsible not only for switching power supply according to the principle of “vkl-swing” and “forward-forth”, but also provides smooth power adjustment (rotation speed of the cartridge) depending on the pressure on the button. If the instrument at the tool suddenly disappeared, and the drill began to work only at full speed, then there are two solutions: replace the entire button with a new one, or open the burned button and try to repair it.

A little theory.

In the design of the button lies the principle of adjusting the power by cutting some part of the sinusoid of alternating voltage voltage, supplied to the drill electric motor. The deeper the button sinks, the more the sinusoid graph looks fully looks like. And vice versa, with a minimum click on the button, the engine receives the power most fragmented. In the simplified version, the circuit of the electrodern button looks as follows.

The power regulatory element is the thyristor VS1, tearing the load power circuit. The dinistor VD1 is sequentially included in the circuit of the control electrode of the thyristor, which has the ability to pass the current only with a certain range of potential difference between its electrodes. The capacitor C1, loaded through the variable resistor R1, will provide this potential difference the faster, the more the engine engine is the engine and, therefore, the more long the thyristor will open, and the greater power will be led to the load in this half.period of the voltage.

The dependence of the voltage on the load on time. A. full power (no regulation, inclusion without a regulator). B. capacity of about 25%. B. power less than 25%. One half.period (lower on schedule) sinusoids, when the current passes through the thyristor, is completely cut off. So that this does not happen, the thyristor needs to turn on the diode in a parallel to the thyristor.

Search and elimination of faults.

The opening of the EN61058 button is not difficult, it is necessary to push the plastic latches with the tip of the knife and get the contact group from the inside with the electronic board. Next, it is necessary to separate the fee, weave it from the contact group. Instead of a variable resistor, the button applies a more reliable option. a step resistor, which is a multi.position switch, where the resistance of each position corresponds to its permanent resistor. In addition to many SMD resistors, the board contains a capacitor, diode and tuning resistor. Installation of the Tyn612 thyristor and DB3 dinistor is performed in a hinged way.

The most likely reason for the fault of the button, when it does not control the speed (power) of the drill. the fault of the thyristor. If there is no way to check the thyristor on a specialized tester, then the thyristor just needs to be replaced with obviously working. The same applies to the dinistor. Everything else: resistors, diode and capacitor. can be checked directly on the board with a conventional multimeter (after the thyristor is dropped). If the multimeter does not have the function of measuring the capacity, then check the capacitor is not particularly necessary, since the probability of its failure is extremely small.

Repair button on the onpecker

Professor Construction tool always works in extreme criteria, therefore, both the mechanical and electronic part of the peorator has an overstated working resource.

Based on the practice, a tool from brands such as Makita, Bosch or Interskol occasionally blocks during the warranty period, but at some point everything breaks.

One of the more vulnerable places at least some kind of button is considered

turning on with a speed regulator and a reverse switch.

Mechanical breakdown. You are not excluded when the tool falls from a height and other strikes on the case of the peorator. Since the plastic is actually not lending to gluing, the only option for reliable repairs will be a complete change of button;
Ben a button’s contacts burned out. In this case, it will not do without a shift;
Formed upwards on the contacts of the start button. If the plastic case itself is not injured at the same time, cleaning contacts will help to solve the case.

Automatic tire change in car

For this purpose, use an electronic multimeter (tester): you need to join the ends of the peorator fork and press on the start button.

If the multimeter is shown the presence of resistance, means a chain of power tool. Lack of resistance reads a violation of the integrity of the chain.

With all this, you need to realize that you will like the inconsistent not so much in the switch button. You should also check the electronic cable for the presence of fractures, the degree of wear of coal brushes and the contacts of the reverse.

Only of course to make sure that the reason lies specifically in the switch.

In the bulk of the Makita peorators (in the models of HR2020, 2432, 2440, 2440F, 2450, 2455, 2475 and 2641), a typical switch of the TG813TLB-1 series is used.

To conduct his audit and/on a different shift, you need to prepare subsequent tools:

The procedure for performing the repair/change of the power button on the Makita 2450 Poorator is subsequent:

We disassemble the electronic part of the tool. For this purpose, it is necessary to unscrew the three mounting screws on the back of the handle with a cross blade and remove the plastic cover.
Next, you need to discard the brushes and extract the TG813TLB-1 switch itself.
To disconnect the switch, you need to remove from it that it remains to make our client a wire. Network wires (brown and blue) are attached with a screw.shaped clamp and having its troubles will not appear. to throw off two wires, quite weaken two screws. Other wires are mounted on self.loading connectors, and in order to extract the wire, a spoke or awl is useful, which are inserted into a special hole and open the clamp. Similarly, they are alternately removed what remains to make our client of the wire. To carry out the repair, it will not be unnecessary to have a pattern for connecting the Peorater button, therefore we recommend that you draw a conditional circuit before removing the wires or take a photo on the phone so that there are no questions when connecting the latest button.
Connecting the latest button. The wires are simply inserted into automatic clamps in full, network wires are fixed with screws.
Next, you need to install the button in the landing hole, return the brush to the destination, install and fix the rear cover of the handle with 3 screws.

Replacement of the peorater button and about repairing washing.

Often, even a professional technique is rapidly burning. This is due to the operation of the tool with a significant overload of the electric motor. The unit should not be overheated, at times it is necessary to make technological pauses. With the harsh breakdown of the peorator, it is a consequence of a negligent appeal with an inventory at one time of operation or during storage.

After each use, it is necessary to carry out painstaking cleaning of the peorator from dust. With a soft cloth or a napkin, you should wipe not so much the housing of the power tool, but also additional ventilation grooves.

It is unacceptable to introduce a peorator outside the premises at one time of the rain and snow.

Often, an inspection of coal brushes should be carried out, which are a responsible part of the electrocope. they carry out the current to the collector and wear out evenly during use and require a change.

Non.original components of an incomprehensible properties should not be taken, which lead to more significant breakdowns.

Replacing the button in electric

Quite often, the electric drill stops working due to the breakdown of its button (it does not turn on, the number of revolutions is not adjusted), we disassemble the drill try to do something, and when we understand that the case is in the button, many wires are already torn from it and which is unknown where it was unknown? You buy a new button, and how to connect it?To do this, you will need a diagram of its connection:

Connection button where the capacitor has three outlets

In order for the engine to start working in the opposite direction, you need to change the wires to the brushes (in the button with a reverse, this is done using the switch lever).

What is a multimeter (?

One of the most popular, especially in everyday life, the modes of the multimeter is a “call”. It is with the help of this function that you can find, a break in an electric circuit or a short circuit, and this often allows you to quickly diagnose and eliminate the malfunction.

The simplest method of connection without a button, in a simple drill (I connected my Albin this old Soviet drill) with a slightly functional button, looks like this: at the entrance and output of the wires of the same color, we twist them together (naturally, turn off the drill from the outlet ), after twisting, thoroughly isolate.

Pershot recommendations

As you can see, to repair the peorater with your own hands is the task that anyone can cope with, the main thing is to deal with the device of this useful tool in the house and follow the instructions. And in order to reduce the appearance of a breakdown to a minimum, some rules are required to follow:

Before you start working with the tool, inspect it for chips or cracks in the case. In case of detection, do repair.
Get acquainted with the instructions and technical passport of the product and follow all the recommendations for working with it.
Use high.quality cores that are suitable for a specific type of materials.
If the volume of work that needs to be done is large, then it is necessary to take breaks in order to avoid overheating.
After working with the tool is finished, clean its surface from dirt and dust, you can also use a vacuum cleaner to blow it.
Follow storage conditions. The peoporator should be in a special place where moisture does not penetrate, since it can damage electrical details.
Carry out full analysis, cleaning and lubrication of the tool on a regular basis once or twice a year.

By the way, the absence or lack of lubrication is a rather common cause of damage to the penetrator. The instructions for the device should indicate which places and parts must be lubricated and which

It is important to know that for gearboxes, a liquid lubricant should be used, which must be poured into a specially designed hole, for other parts you can use a more thick lubricant

Thanks to compliance with these simple rules, the tool will serve as a long time, and the risk of malfunctions will be minimized. But if any malfunction appears, then following the recommendations above, you will eliminate it without difficulty.

Useful tips

Often, even professional equipment quickly fails. This is due to the operation of the tool with a significant overload of the electric motor. The power unit should not be overheated, it is periodically necessary to do technological pauses. Sometimes a serious breakdown of the penetrator is a consequence of careless handling of tools in or during storage.

After each use, it is necessary to carefully clean the peorator from dust. With a soft cloth or a napkin, not only the housing of the power tool should be wiped, but also the ventilation grooves.

The use of the peorator outside the rooms during rain and snow is unacceptable.

It is regularly carried out by inspection of coal brushes, which are a responsible part of the electrocope. they conduct current to the collector and gradually wear out during operation and require replacement.

Do not buy non.original components of dubious quality, which can lead to more significant breakdowns.

How to determine the performance of the button?

To do this, you need a regular multimeter (tester) and screwdriver.

The diagnostic process itself is carried out as follows (on the example of a common model of the DWT SBM-500 drill):

Remove the lid of the drill housing, unscrewing several mounting bolts;
Unscrew two screws on the clamp of the network cord;
We remove the block button block, disconnect the reverse switch (it is usually attached on the clips that bend it slightly). The reverse itself is sold separately and it can also be replaced if necessary;
We take the multimeter, set the switch to the sound signal position. Close the tester contacts to make sure of its performance (the device must give a sound signal);
We call the button. To do this, we put one contact of the tester on position 2 (it must come into contact with the wire), put the second contact on the screw that presses the wire 220 volts. When the button is pressed, the device must make a sound signal. If this does not happen, the button does not work.

How to replace the button?

To do this, you need a flat screwdriver and a regular pin or thin awl.

The process of replacing the button is made in the following sequence (for the example of the DWT SBM-500 drill):
We unscrew the two screws pressing the network wire, take it out;
We insert the awl into the hole of the wire running from the stator, take out the wire along with the awl.
We carry out a similar manipulation to extract the second wire. If you are afraid to confuse the wires when connecting a new button, we recommend drawing a conditional connection scheme for connecting the drill on;
We take a new button and connect the wires of the network cord to it in accordance with the drawn circuit. Then we connect the drill itself to the button. The wires from the stator are simply inserted into the holes to the stop;
We attach the reverse button to the block;
We install the block in the seat in the drill housing, carefully lay the wires, press the network cord with two screws;
Close the lid of the drill housing, conduct a test.

How to replace and connect the power button to the drill. phased instruction

The device of the drill button is very simple: when pressing, the key glides in a special block along the guides and pusher closes the contacts, starting the electric motor.

In the process of long.term operation in conditions of repair (dust, moisture, etc.P.) Curve accumulates inside the start button block, which prevents the full movement of the pusher and blocks it.

Therefore, before buying a new button, you should try to clean it. This defect is eliminated very easily. you just need to open the block and remove dirt from it with a brush. If the contacts are formed on the contacts, it should be cleaned with small sandpaper. In case of contact of contact, it is necessary to replace the entire block.

The principle of operation and the main nodes

The drill owes its appearance to the demand for underground drilling to replace manual labor with automated. In 1870, the American inventor Simon Indersoll was represented by the ancestor of the shock drill. In his work, the tool used a steam drive and a drill. The appearance of electric motors at the end of the 19th century allowed to improve the tool. So, in 1889, engineer Arthur James Arnot proposed using the electric motor together with the drill, and already in 1895 an instrument appeared, freely retaining when working in his hands.

At the beginning of 1917, Arthur Arnot, working on BlackDecker, connecting a button to the drill and adding a pistol handle, made the device one of the most popular power tools in the world. Since then, the design of the electrodegro has not undergone cardinal changes.

The classic drill works only in drilling mode, but with the development of manufacturing technology, modern devices began to be equipped with a shock mode. When connecting to the 220 volt network, the gearbox, converting the electrical energy into a mechanical one, makes a cartridge connected to the mechanism of the device, make rotational movement. The number of revolutions of the cartridge is controlled using a rheostat mounted in the power button, and the direction of rotation is set by a reverse. The drill clamped in the cartridge, due to its shape and under the influence of high speed, easily performs the hole in solid or soft material.

To make a blow in the device, reciprocating movements arise due to the work of the motor are used. A ratchet representing a gear ring is installed on the axis of the location of the cartridge, and the teeth are performed on the housing that create the emphasis. Когда ударная дрель переключается в режим «сверление с ударом», храповик зацепляется за упор, а затем с него соскальзывает. The shaft makes blows in the vertical direction.

Before starting the repair of the drill with your own hands, it is necessary to determine which part of it needs to be restored.

The main parts of the drilling tool are:

capacitor;
engine start and stop button;
revolutionary control device;
reverse switch;
bearings;
electric motor;
engine cooling device;
gearbox;
return spring;
chuck;
Corps elements.

Thus, the electroderley nodes are divided into electrical and mechanical modules. It should be borne in mind that the shock node has low performance and with frequent use of such a mode in the work quickly wear out.

The wear of the shock unit not only negatively affects work on the chopping, but also increases the load on the electric motor, forcing it to overheat.

The device electric motor

The engine is the main element of the device that acts in the tool gearbox. It consists of a stator and a rotor, while the rotor is a mobile part, and the stator, respectively, is not. The rotor design includes anchor with the collector. An anchor is an element of an engine assembled from steel plates. On them, windings from the electric current of the material. copper. copper are wound. The collector is a cylinder. It is made from the dielectric and the current of the plates, the anchor windings are connected to these plates.

Due to the magnetic flow created around the anchor, the stator windings, its rotation occurs, which leads to the occurrence of the moment of twisting. The magnetic flow that occurs under the action of direct current is always directed only in one direction.

the food of the food for the windings occurs by means of brushes made of graphite. The brushes are located in such a way that they provide constant electrical contact with the anchor.

The wear of the brushes should not exceed 70–80 percent, if this value is higher, then the contact worsens, as a result of which sparking occurs in this place. Before replacing the brushes, you should pay attention to the brush holder and, if necessary, clean it. Thus, the main parts of the electric motor are:

Checking of windings is most easily carried out by a multimeter. To do this, with one contact wire of the measuring device, the brush holder is concerned, and the second is touched to the contacts of the inclusion in 220 volts. If the tester shows endless resistance, then this means blocking the winding. The working resistance of the stator winding is in the range of 30-60 Ohms. For example, in the popular electric drill Interskol Du-13/580 ER resistance is 40 Ohm. When replacing the stator, you will have to disassemble the engine. For this, four screws are unscrewed and the case is dismantled to two halves. As a result, access to other parts of the engine is exempt.

The anchor connects to the gearbox. Often, visually examining it, we can conclude that its integrity. There are no scratches and blankets on the anchor. When replacing the anchor, it is important to correctly install a bearing with a rubber gasket. It is possible to measure an anchor with a simple tester only for a break in the winding, but for verification for an interval circuit, a specialized device will be needed. The measurement is made in the mode of checking the resistance between the anchor windings on the lamellas. The resistance between all lamellas should be the same.

Revolution regulator

The power tools of the power tool are controlled by a simystory regulator located in the button to turn on the device on a special gasket made of textolite. When you press the button on the control of the simistor, variable voltage is applied. The symistor opens and the current enters the load. When the polarity at the inlet changes, the semiconductor device closes. Then everything is repeated in the cycle.

As a result, the signal at the output of the Simistor will have the form of impulses. The larger the signal level is supplied to the semiconductor, the more time it is open, which means that the pulse length at its output is greater. The degree of opening of the simistor is regulated by variable resistance that limits the signal that is supplied to the semiconductor.

In addition, the speed of rotation of the cartridge into the electrodele depends on the force of pressing the launch button. This is realized by connecting a button with a speed regulator. Drinks, depending on their type, may have a different circuit of the circuit breaker, but its device is the same. In the case of the buttons, the contact group and spring.loaded plates (resistors) are placed in the case. These plates are made in the form of sliding contacts.

Additional devices

Using special devices for various purposes for a drill, you can expand the functionality of this universal tool. You need to purchase them separately, but you will never regret the money spent, because special nozzles turn an ordinary drill into a grinding machine or a mini-drain for home needs. With the help of corner nozzles, you can work as a tool in an inaccessible place or turned it into a cutting cutter, setting a nozzle with the original name cricket.

Special guides make possible work strictly at a right angle, for vertical drilling, special conductors or factory manufacturing of the rack are used, turning the drill into a drilling machine.

Regardless of which model the user uses, it requires constant care: after any, even the most short.term work, it is necessary to wipe the case of the product from the dust that has caught, paying special attention to ventilation holes. so that the dust and small waste from drilling do not get inside the product.

If you are not going to use the drill for a long time, then all the metal parts must be lubricated with a thin layer of technical oil. this will protect them from the effects of ubiquitous corrosion. Carry out periodic examinations of internal details, especially applies to the sequins of the electric motor. do not allow their limit wear. If you fulfill these recommendations, then your tool will not need repairs in the near future.
