The famous Japanese brand Makita enjoys well-deserved popularity among consumers around the world. All products of Makita brand are highlighted by high quality, ergonomics, available prices. And the competent Russian consumer tries to squeeze out of the tool more than it can give. Makita's ushm have their limiting strength.

Repair of the Makita's Bulgarian do it yourself does not represent a special complexity and can be performed as in service centerAnd independently, since you can freely purchase the necessary parts. The malfunctions of the grinder and their elimination methods are discussed in detail in the attached instructions.

Features of the design of the Bulgarian Makita

Bulgarian is a negliform machine that received such a name only on the expanses of the former USSR. Structurally, any corner car (USM) is arranged equally.

The principle of operation Bulgarian Makita is based on transforming electrical Energy in mechanical. This leads to the rotation of the shaft to which the cutting disk, grinding, polishing is installed. And it is called the corner for the reason that in the gearbox used, the torque is transmitted at an angle of 90º.

Since the cooling of the electric motor in Makita's grinders is ensured by suction of external air through ventilation holes, Makita Bulgarian workers are coated with a special protective powder varnish that prevent dust sedimentation. Structurally in the grinders of Mcita provides a labyrinth system of seals and a sealing "Start" button.

But each company to attract the buyer introduces its highlights into the design. Not deprived of this and Bulgarian Makita. Make's Bulgarians are conventionally divided into powerful and small.

Makita Bulgarians are marked depending on the power of the electric motor.

TO constructive features Cellular Makita machines include:

• The presence of a labyrinth device protecting bearings from dirt and dust.
• Motor winding in high-power grinders are protected by armored coating.
• Makita corner machines are equipped with a special system that protects the tool from jerks when started, called Super-Joint-System.

A few words about the SJS system. The system prevents the impact of the reverse strike, eliminates the jerks and the jumper of the working body, protects the electric motor from overloads.

The system uses a spring, the purpose of which, transmit effort from the rotor on the gear gear. The spring performs the role of buffer, prevents the appearance of jerks when starting and stopping. This design significantly reduces the vibration and provides smooth operation of the Makita USM

Makita Bulgarians are divided into classes in the size of the work disk width. Bulgarians are conditionally divided into three classes: lungs, medium, heavy. In turn, each class is divided into grinders for professionals and for household needs. Professional models Bulgarian Makita has an increased power supply, an integrated security system, an enlarged working resource. Professional grinder perfectly withstand heavy loads for a long time.

Makita household corner machines have high performance featuresBut very democratic prices. Bulgarians Makita can use a disk with a maximum diameter of 230 mm.

Depending on the diameter of the disk and divine Makita to classes:

• The diameter of 115-125 mm characterizes the light class. Easily hold one hand for the housing that performs the role of the handle. But professional grinders of this class can be equipped with a back handle in which the instrument's power button is built;
• The diameter of 150-180 mm refers Makita grinder to the middle class. This category includes professional and amateur models equipped with electric motors of different power. W. modern models A swivel back handle is installed;
• The diameter of 230 mm characterizes the grinder of a heavy class. In this class, Makita's Bulgarians are produced solely for professionals. These machines are designed to work on concrete, stones, bricks, etc. In their designs all laid modern systems protection of the consumer from injuries.

Makita Bulgarian models are available for disks with diameters of 115 mm, 125 mm, 150 mm, 180 mm and 230 m.

In the grinders of high power there is a replacement of coal brushes without removing the cover of the stator housing.

Makita Bulgarians different power differ in appearance. Professional Bulgarians have a capacity of over 1000 W large housing and a comfortable back handle. The handle is equipped with protective anti-vibration linings of black. The grinders with a capacity of up to 1000 W have a convenient housing that performs the role of the handle.

On the makita makita is a quick-release casing. This design allows you to quickly remove the protective casing.

Required tool

Repair with your own hands of Makita corner machines, requires the use of a specific tool. Do not do without a screwdriver. It is preferable that they are equipped with a snoring mechanism. The best way, use the battery screwdriver. To repair the electric part of the macita, the tester will need, the device for determining the short-circuited turns of IR-2. And still harvest the horn key, the puller of bearings, a hammer, a copper of a soft metal. Well, do not do without the right lubricants , woolproof materials, liquids for washing the old lubricant.

We begin to start repairing your own hands with the preparation of the workplace, installation right lighting. You will need a circuit of a corner machine of the desired model and the proposed instruction.

Any malfunctions of power tools are divided into two types: electrical and mechanical.

Consider the repair of nodes of the Makita Bulgarian nodes will be on the example of the Makita 9565 ESM scheme.

Possible electrical malfunctions

Makita Bulgarian Electrofunctions can be divided into control circuit faults, rotor failure and stator malfunction.

How to eliminate malfunctions in Makita Bulgarian Control Chains

If your BulgarianAkita does not turn on, the greatest reason can be a breakdown in power and control circuits.

To get to the components of the control circuits, it is necessary to remove the housing cover of the case pos.38, twisting the self-seed screw of 4 × 18 pos.39. Switch ST115-40 K9565 pos.28 is attached to the switch holder pos.27. The switch holder is closed with a lid pos.29, which is attached on the motor housing Pos.33.

The switch is suitable for the power cable pos.37. Using the tester, check the integrity of the chains from the plug contact to the switch terminals. Switch posing.28 is controlled by lever pos.30. From the contacts of the switch, check the chain to coal brushes pos.42.

In the chains of control of the weak link are coal brushes. In Bulgark Makita 9565 applied coal brushes CV-318 with Avtovascular, so check the brushes.

Roll regulators are installed in professional grinders. In the macitol grinders with a power of more than 1000 watts, the installation of a soft start system is provided. Such a system is equipped with a Makita 9077SF ESM.

When the switch fails, the fault is eliminated by its full replacement. When cutting or breakdown feeding the wires, the fault is eliminated by replacing the whole wire or removing damaged parts.

The inclusion process is carried out using the lever pose .30. If you disassemble the body of the grinder for repair or maintenance, in front of the assembly, lubricate the grooves for the movement of the silicone lubricant.

Checking the electric motor

In addition to the control circuits in the electric scheme, the grinder includes a rotor and a stator. These are complex nodes that are recommended to be carried out in specialized centers. But for Russian craftsmen there is nothing inaccessible. We recommend our own.

How to repair the stator Bulgarian Makita

For the failure of the stator posing.24, the Bulgarian indicates the appearance of the smell of Gary, overheating the body of the grinder, spontaneous set of turns of the grinder. In the body of the grinder poses.33, the stator is attached to four saming screws 4 × 70 pos.21. To prevent damage, the stator closes the protection of pos.20.

The repair of the stator Bulgarian Mcita is to determine the short circuit or cliff windings. It is best to perform the diagnostics of the stator with a special device called IR-2. The stator is considered faulty if traces of the winding darkening are visible, a breakdown or a short circuit of the winding turns is determined.

Simply. It is necessary to rewind its windings.

How to repair the rotor of the Bulgarian Makita

With overheating of the grinder, the appearance of the smell of Gary, increasing sparks in the collector area it is necessary to pay attention to the integrity of the rotor post.13.

Scheme of Bulgarian Mcita

The rotor dismantling is associated with the execution of a sequential disassembly. To remove the rotor, it must be released from the gearbox. To do this, unscrew the hex nut M6 pos.4. To unscrew the nut, you need to push the rotor one hand. The second hand, with the help of a horn key, unscrew the nut counterclockwise.

Remove the nut, pull the flat puck pall. 5, remove the conical spiral gear pose 6, remove the locking spring pos. 7. Shaking the rotor on the sides gently pull it out of the gearbox case pose.3. Removing the locking ring pos. 8, with the help of the puller, check the bearing pos. 9.

Makita 9565 Bearing is used 6001LLB bearing.

It remains to remove the flat washer pos.10 and the gearbox lid pos.11.

Before you appearance Makita 9565 Bulgarian Rotor with a molded insulating washer pos 144, a flat washer 7 pos.15, bearing pos 18 and boot rubber 22 pos.17. Bearing 627zz is used in the grinder from the collector. Russian analogue 80027.

Rotor repair is to replace it with new or repaired. You can repair the rotor on your own, but it is necessary not only for patience, tooling, material. This is a type of high class work.

Mechanical damage

In addition to the electrical part, the mechanical part is also included in the grinder, the main node of which is the gearbox.

How to repair the gearbox

The gearbox consists of a hull leading and driven gear. The leading gear is hoping for the Rotor shaft. The driven gear is attached to the spindle pose. 50.

On the Bulgarian Makita 9565 driven gear pressed on the spindle. And in the Makita 9558HN Bulgarian model, the driven gear is mounted on the shaft with a sponge groove.

The reductions of the gearbox are associated with the failure of the gear teeth. Gears are licking or cleaved part of the teeth.

Makita Bulgarian Reducer Repair is to replace the pair of osospheric gear. The replacement of the gear is made only in a pair.

To remove the slave gear, do not do without a press or a special puller. Do not use the hammer, since the gearbox is made of fragile material.

Bulgarian assembly Makita 9565

Before assembling the Bulgarian Makita, check the integrity of all parts, their cleanliness. The assembly starts from the installation on the bearing spindle and the driven gear.

Spindle assembly

The spindle pos.50 is put on the boot pose 51, the case cover Pos.53, the bearing housing Pos.54. In the bearing housing, insert the pre-lubricated bearing 6201LLB. Press the slave gear pose 56. on the spindle. Spindle is assembled.

Installing the rotor in the gearbox

A renovated or new rotor with riddled bearings insert into the gearbox housing, wear, according to the drawing, all the details, fit the lead gear and lock the nut.

In the process of installing the rotor in the gearbox housing, control the reducing the bearing. The correctly installed rotor is easily rotated in the gearbox housing.

Installing the rotor in the stator body

The collected gearbox with the rotor is inserted into the stator body, which is pressed by the bearing. from the collector, closed by a protective rubber boot, and the ease of scrolling is checked. It remains to install the collected spindle in the gearbox housing.

Insert the collected spindle into the gearbox housing pose.3, after paving the rubber ring pos.55 and smearing the bolts pose 52 with a sealant.

All operations on the assembly of the mechanical part of the grinder are accompanied by mandatory parts. Special attention Take the process of imposing lubricant into the Reducer of the Bulgarian.

It is important not only its quality, but also the quantity. A lubricant in the amount of 1/3 of the gearbox volume is stacked into the bacal gear gear housing.

Collecting the mechanical part of the grinder, each time before twisting the fastening screws, check the ease of rotation of the gearbox by checking it for the spindle.

On the final stage It remains to install coal brushes, wear the back cover of the case and check the working capacity of the tool.

CB-325 coal brushes are installed in Makita 9565 baccakes. The timely replacement of coal brushes will not only retain the rotor, but also will prolong the service life of the entire tool.

As a rule, coal brushes are changed after 7000 hours of operation or with wear up to 8 mm of length. In EC stricted cases can be used. But at the first opportunity it is necessary to install relatives.

If your Bulgarian works after the assembly without foreign noise, without jerks, you can congratulate you. The Makita Bulgarian Repair Task is performed.

Even the most qualitative tool after a while may break, not to mention the cheap "Mortgage". Bulgarian is also no exception. This tool has gained popularity due to its multifunctionality and convenience in work. Exists a large number of Bulgarian models, the device and the principle of operation is not significantly different from each other. During operation, the tool may break. Repair in the workshop will be released in the round sum, so many craftsmen carry out the repair of the Bulgarian with their own hands.

Bulgarian device

Bulgarian in many cases is an indispensable thing. As with any other tool, it should be contrary to it quite carefully. To fully repair the grinder with your own hands, you need to know how it is arranged.

Anchor.

This item is located inside electric engine And during the work begins to rotate. The higher the speed of its rotation, the greater the power of the Bulgarian.

Collector.

Represents separate place Anchor on which managers and power windings are located. Using the collector, the signals are served on the control unit and the engine.

Electric brushes.

These elements used to sum up From the power cable to the collector.

Reducer.

Located in the front of the Bulgarian. Thanks to him, mechanical energy from the anchor to the disk is transmitted during the rotation.

It is one of the parts of the engine with an anchor located inside. This the item in its design is the most difficultbecause all windings are very precisely pressed in it.

In addition, its body includes a cable with a fork and holder knobs.

Before you begin repairing the grinder with your own hands, it is best to have in front of you layout and electrical scheme and detailed instructions which corresponds to a specific model. Repair the tool with your own hands, possessing certain knowledge.

Repair Bulgarian

By repairing any tool, usually start from the simplest and finish the most difficult. Carrying out the repair of the grinder with their own hands, also adhere to this rule.

There are situations that the tool ceases to work and does not turn on. The reason for this most often lies in the fact that the brush ceases to do electricity. The whole problem in this case will be either in the wire or in the fork, or simply broke the starting mechanism. To eliminate malfunction should disassemble the grinder and checkwhether there is no breaks in the cable. As soon as the wire is replaced, the tool begins to work normally.

Bulgarian does not work, but the wire and fork are not damaged. In this case, the repair instead will be to ensure that the starting mechanism is disassembled. All items that will be removed must be labeled. This is done in order to subsequently can be collected correctly. Otherwise, it can scram anchor or burn the winding. The trigger brushes can be selected any such button.

If the starting mechanism and the wire are in order, but the tool still does not work, then the problem is most likely in the holders of the brush. Usually, to appear the spark and launch of the mechanism, it is necessary to clean the plates with contacts. In case of failure, replace the available feet. Usually they are smoothly working for about two years. It should be noted that some models of Bulgarians have brushes compound. In this case, the new one should only be installed in the kit. Partial replacement can not be made.

After replacing the old clearly to the new, it is necessary to examine them carefully. If uneven wear is clearly visible, it means that the mobile part of the grinder or the center of gravity shifted. In this situation it is worth contacting a specialistBecause it is almost impossible to eliminate the fault and adjust the center of gravity with your own hands.

More than defined faults, the repair of which requires gear skills and knowledge, are considered:

• bearing jamming;
• failure control electronics;
• deformation of the hull;
• breakdown of teeth casing gearbox;
• failure of a stator or anchor;
• caller failure.

If there are mechanical defects of the grinder, then you need more attention to pay the state of a large gear, shank and sleeves. If uneven wear of the shab shaft or teeth are detected, then it is necessary to replace the worn parts as quickly as possible.

Operating Rules

In order to avoid repairing a grinder with their own hands, it is necessary to observe the following important rules operation.

If your arsenal has an old angular grinding machine, do not hurry to write it off with accounts. Using an easy electrical circuit, the device can be easily upgraded by adding a function of changing the frequency of revolutions. Thanks to a simple regulator who is actually assembled by its own hands in a few hours, the functionality of the device will increase significantly. Having reducing the frequency of rotation, the grinder can be applied as grinding and sharpening machine for different species Materials. New features appear for the use of additional nozzles and snaps.

Why is Bulgarian low revs?

The built-in disk speed control function will allow to delicately process materials such as plastic or wood. Low revolutions increase comfort and safety. This feature is particularly useful in electrical and radio-based practice, in car service and restoration workshops.

In addition, among professional users of the power tool, there is a steady opinion that the simpler the device is arranged, the more reliable. And the additional service "minced" is better to take out the limits of the power unit. With this situation, the repair of equipment is greatly simplified. So some companies specially produce remote individuals electronic regulatorswhich are connected to the machine cord of the machine.

Roll control and smooth start - for what you need

In modern grinders, two important functions that increase the reliability and safety of the instrument are used:

• roll control - a device designed to change the number of engine speeds in various modes of operation;
• smooth start - a diagram that provides a slow increase in engine speed from zero to maximum when the device is turned on.

Used in electromechanical instruments, in the design of which the collector engine is used. Contribute to a decrease in the wear of the mechanical part of the unit during inclusion. Reduce the load on the electrical elements of the mechanism, launching them to work gradually.

As studies have shown the properties of materials, the most intensive working of rubbing nodes occurs during a sharp transition from the state of rest to the speed of fast movement. For example, one launch of an internal combustion engine in the car is equal to the wear of the piston group to 700 km of mileage.

When the power is turned on, a jump-shaped transition from the rest of the rest to the rotation of the disk at a speed of 2.5-10 thousand revolutions per minute. Those who worked with the grinder, it is well known the feeling that the machine simply "breaks out of the hands." It is at this moment that there is an overwhelming amount of breakdowns associated with the mechanical part of the unit.

The stator and rotor windings are also experiencing no less. The collector engine starts in a short circuit mode, the electromotive force already pushes the shaft forward, but the inertia still does not allow it to rotate. There is a start-current jump in the coils of the electric motor. And although they are structurally designed for such work, sooner or later, the moment comes (for example, when the voltage jump in the network), when the insulation of the winding does not withstand and intersective closure occurs.

When you turn on in the electrical scheme of a smooth start circuit tool and changing the engine speed, all of the above problems automatically disappear. Among other things, the problem of "failure" of voltages in the total network is solved at the time of launch hand tool. And this means that the refrigerator, the TV or computer will not be susceptible to the danger of "bravery". And the safety machines on the meter will not work and turn off the current in the house or apartment.

The smooth start circuit is used in the grinders of medium and high price categories, the speed adjustment unit is predominantly in professional USM models.

Adjustment of revolutions allows you to handle with a grinder soft materials, Perform a thin grinding and polishing - at high speed, the tree or paint will simply burn.

Additional electrical circuits increase the value of the tool, but increase the service life and the level of security during operation.

How to assemble the regulator scheme with your own hands

The simplest power regulator, suitable for the grinder, soldering iron or light bulbs, is easy to assemble with their own hands.

Concept electrical scheme

In order to assemble the simplest revolver regulator for the Bulgarian, you must purchase the items depicted on this scheme.

Schematic scheme Rollover regulator

• R1 is a resistor, resistance of 4.7 com;
• VR1 is a rapid resistor, 500 kΩ;
• C1 - condenser 0.1 μF x 400 V;
• DIAC - Symistor (symmetric thyristor) DB3;
• Triac - Simistor BT-136/138.

Work scheme

The VR1 trimmer resistor changes the C1 capacitor charge time. When the voltage is applied to the circuit, at the first point of time (the first semi-dimension of the input sinusoid) Simistors DB3 and TRIAC are closed. The output voltage is zero. CONDER C1 is charging, the voltage on it increases. At a certain point in the time defined by the R1-VR1 chain, the voltage on the condenser exceeds the DB3 Simistor Opening threshold, the simistor opens. The voltage from the condenser is transmitted to the TRIAC simistor control electrode, which also opens. Through the open Simistor begins to flow. At the beginning of the second half of the sinusoid sinusoids, the simistors are closed until the C1 capacitor recaptures in the opposite direction. Thus, a pulse signal is obtained at the output. complex formwhose amplitude depends on the operation time of the C1-VR1-R1 chain.

Order assembly

The assembly of this scheme does not make it difficult even a novice radio amateur. Spare parts are available, you can buy them at any store. Including and fall from the old boards. The procedure for assembling a regulator on thyristors Next:

How to connect the device to the grinder, options

Connecting the regulator depends on what type of device is selected. If used simple scheme, It is enough to build it into the power tool power tool channel.

Installation of self-made fees

There are no ready-made recipes for installation. Anyone who decided to equip the ESM regulator has it in accordance with its goals and tool models. Someone inserts the device into the holder handle, someone in a special extra box on the case.

In various models, the space inside the bacal casing can be different. Some are enough free space To install the control unit. In others, it is necessary to take it on the surface and secure in a different way. But the trick is that, as a rule, a certain cavity always exists in the back of the instrument. It is designed to circulate air and cooling.

Cavity in the back of the apparatus

Usually here is the factory revolver regulator. Made with your own hands can be placed in this space. So that the regulator does not overload, thyristors should be installed on the radiator.

Video: Smooth start plus and engine speed adjustment

Features of the finished block

When buying and installing a factory regulator inside the grinder, most often you have to modify the housing - cut the hole in it to output the adjusting wheel. But this may adversely affect the rigidity of the casing. Therefore, the installation of the device is preferred.

Adjusting wheel changes turns

The numbers on the adjusting wheel indicate the number of spindle revolutions. The value is not an absolute, but conditional. "1" - minimum turns, "9" - maximum. The remaining numbers are used for orientation when adjusting. The location of the wheel on the housing is different. For example, on the Bosch PWS 1300-125 CE, WortEx AG 1213-1 E or WATT WWS-900, it is located at the base of the handle. In other models, such as Makita 9565 CVL, the adjusting wheel is in the end of the casing.

The diagram of connecting the controller to the grinder is not complicated, but sometimes it is not so easy to stretch the cables to the button, which is located on the other end of the instrument housing. The task can solve the selection of the optimal cross section of the wire or the output of it on the surface of the casing.

The regulator is connected according to the scheme

A good option is to install a regulator on the surface of the device or fastening to the network cable. Not always everything is obtained from the first attempt, sometimes the device has to be tested, after which make some adjustments. And it is easier to do when access to its elements is open.

Important! If there is no experience with electrical schemes, it is more expedient to purchase a finished factory regulator or an ush, equipped with this feature.

Mounting to the network cord

Device operation manual

The main rule during the operation of the grinder with a self-made regulator of revolutions - compliance with the mode of operation and recreation. The fact is that the engine operating on the "adjusted" voltage is particularly heated. When grinding on low revs, it is important to make frequent breaks so that the collector winding is not burned.

It is also extremely recommended to include a tool if the revolve regulator is set to a minimum - low voltage is not enough to scroll through the rotor, the collector lamella will remain in short circuit mode, the windings will start overheat. Unscrew the variable resistor to the maximum, then turning on the EARM, reduce the speed to the desired value.

Compliance with the correct order of inclusion and adjustment will allow the Bulgarian to be operated indefinitely for a long time.

In addition, it should be understood that the adjustment of the speed of revolutions on the grinder occurs on the principle of water tap. The device does not increase the number of revolutions, it can only lower them. It follows from this that if the maximum passport speed is 3000 rpm, then when connecting the revolt controller, the Bulgarian will operate in the range below than the maximum speed.

Attention! If the USM already contains electronic circuits, for example, already equipped with a regulator of revolutions, then the thyristor regulator will not work. Internal schemes The device simply does not turn on.

Video: Homemade voltage regulator

Equipping the Bulgarian engine speed control circuit will increase the efficiency of using the device. and expand its functional range. It will also save the technological resource of the grinding machine and increase its service life.

To date, stores have a very great choice of power tools. They all differ in both the price and functional features and reliability. Almost all modern models of electrodarls, jigsaws, screwdrivers have a revolve regulator. But the grinders with such an opportunity occur very rarely, and if there is, it is much more expensive. So as not to overpay too much, I decided to equip my bangcake purchased long ago. For cutting metal cutting stone, the regulator is not needed in principle, but for grinding of the enclosures in amateur practice, it simply will not be replaced.

Bulgarian Roll Control Concept

So, the regulator scheme. She is very simple, and on our forum there is a topic for her discussion. Even for a novice radio amateur, it is not difficult to collect her. Details are not expensive, and they can easily buy them in the store, or drop off from old boards (if they are of course there). You can collect and separately in a box with a socket. Then use it as carrying with power regulator. For some time I had it. After tired of it with carrying, and I gathered a regulator in the handle of the grinders.

First you need to collect all the details in a bunch. Unscrew the grinding handle, and think over the location of each diagram element. IN different brands Grinders are different handles, and how you place everything there, and indeed, everything will fit there - this is already your concern. In the extreme case can be collected in a separate box.

The radiator cut out of a piece of aluminum. It was screwed by a simistor. By the way, he does not heat up much when working, so the radiator can be done with a small area. Further soldered all the details attachment According to the scheme.

So that when working it all the case did not cease and did not hurt - blew epoxy resin. A variable resistor installed on the other hand. It was put on a large plastic handle. Even when working with it, it is convenient to change the rotations of the grinding circle.

In the last article, I told how to connect and start an engine for 380 volts in a single-phase power grid 220 V. Now I will tell you how to connect a single-phase electric motor from a broken washing machine, a vacuum cleaner, etc. It can be successfully used for other purposes in household, for example, for the drive sharpened, polishing machine, lawn mowers, etc.

220 volt collector electric motor circuit

In electrical drills, perforators, grinders and some models washing machines Machines are used synchronized collector engine. It successfully launches and works in single-phase networks No extra launchers.

For, to connect a collector electric motor, It is necessary to connect to each other with a jumper two end number 2 and No. 3, one coming from the anchor, and the second from the stator. And the remaining 2nd end attach to the power supply 220 volts.

Remember that when connecting the collector Electric motor without electronics block, it will only work on maximum speed, and when starting it is a strong jerk, a large starting current, sparking on the collector.

There may be a motor and 2 high-speed, then 3 end from half of its winding will go from the stator. When you connect to it, the rotation speed of the shaft will decrease, but it increases the risk of insulation disorders when the motor is started.

To change the direction of rotation, it is necessary to change the seats of the editor or anchor ends.

Schemes for connecting single-phase asynchronous electric motors

If only one winding in the stator would be in single-phase electric motors, then an electromagnetic field would be pulsating, and not rotating. And the launch would only happen after the collapse of the shaft hand. Therefore, an auxiliary winding is added to independently launch asynchronous engines, in which the phase with a capacitor or inductance is shifted by 90 degrees. Startup and pushing the electric motor rotor at the time of inclusion. The main inclusion schemes are shown in the figure.

The first two schemes are designed to connect the startup at the time of the motor startup, but not more than 3 seconds by duration. To do this, use a relay or a start button that you want to press and hold until the motor starts.
