Anchor is one of the most important parts of your power tool. The quality and functionality of the tool depends on how stable and efficient the drive is. The rotor is the part that “distributes” the motor impulses to other parts of the machine. If it breaks, you can no longer use the machine. However, it is not so difficult to solve the problem, because the company “StavBytService” offers anchors for power tools in Stavropol. Our catalog has parts for peoratorov, angle grinder, drills and other power tools of all models and brands (Interskol, StavTool, Bosch, Hitachi, Makita, AEG, Graphite, Sturm, Kalibr, Zubr, Simko, Enkor, P.I.T, Instar, DWT, Flex, Bort, VMX, Resanta, Spets, Stavr, Union, Violent, Wurth, Hyundai, Einhell, DeWALT, Elitech, Mekkan, Diold, Vihr, Crown, Dorkel and others.).

Anchor for angle grinder (angle grinder), a selection of analogues in the online store at the best price

The rotor (anchor) of angle grinder is one of the most important and expensive parts of the tool. Is the moving part of the motor, series-connected windings with the stator by electromagnetic induction convert electrical energy into rotation, through the working shaft of the rotor transmitting torque to the gear mechanism.

How to check the angle grinder armature

If the angle grinder stopped starting, then most likely the cause is:

  • Breakage of the mains cable. easily diagnosed visually and by “probing” with a tester from the plug to the connection to the start button
  • Failure of the start button. also by “testing” the contact of the power input up to the output to the stator, with the button in the on position
  • Brushes are worn out or “auto-stop” function has worked out. take out brushes and check if there is enough graphite body
  • Brushes are “hanging” in the brush holder shaft. check the tightness of the collector-brush node, if it is not enough, remove brushes and carefully clean the brush holder shaft (also, there are “pinned” brushes, the physical size of the body which is not qualified to fit the required. better to replace the original or suitable characteristics and quality of similar)
  • Before final output, inspect stator for lack of power contact (most commonly at the frame connector), and for signs of MH (inter-turn shorting) of windings (can be diagnosed by burnt traces upon close inspection of the removed armature) and check with a tester.

Significant drop in tool power and increased brushes sparking on the collector, also delayed starting, spontaneous speed changes are a clear sign of armature failure. Because of overloading, looseness of the ON-ratio, seized bearings, overloading and overheating can lead to short-circuiting of the windings. Entry of conductive dust causes increased sparks as a result of overheating of the collector blades, up to melting and mechanical short circuit, can also occur from the worsened contact of dust, sawdust, etc.д.

We recommend replacing the defective rotor with a new one. There’s also the option of repairing the anchor, by rewinding the windings. But in practice, the amount of money saved does not compensate for the time spent and transportation costs. Repaired anchors tend to fail quickly, only postponing the solution to the problem for a short time

How to choose an angle grinder anchor

Ideally, find the original rotor for your model of angle grinder, but if it is impractical due to financial constraints and the general condition of the angle grinder (significant wear of the other nodes, and the price of the anchor. 50-70% of the cost of a new tool) or there are none available, or there is no firm confidence in the originality of products, then there is nothing wrong in the selection of analogues. On the market of spare parts, there are sellers who are not squeamish about details of dubious quality, you should be guided by the price.

Wrongly picked up rotor or blatantly cheap spare parts (but not the exception, when low-grade fakes are sold at the price of original parts) most likely will not serve long and can damage other parts of your tool

Also, you can focus on the quality of the winding, the presence and number of balancing holes on the frame and the design of the collector. Varnish coating and evenness are also informative.

Each part can be classified by the physical characteristics necessary for the selection of analogues. With filters, it is not difficult to sort by required parameters. Start with the overall dimensions, then the diameters of the cage, collector, etc.e The drawing is directly on the parts page and is worth checking and confirming with a final check.

  • Overall length is the total length of the rotor, from shaft edge to shaft edge
  • Bearing spacing. bearing seats are clearly defined in the housings, n.е. the distance between the centers of the seats is important, as it affects the density or even the ability to mount the anchor
  • Bearing seat diameter. bearing inner ring seat
  • Collector diameter. the gap between the brush and the collector, as well as the number of blades in the plane, provide the rated operation of the electric motor, but often, enough to match the diameter
  • the length of the frame. the number of winding turns depends on it, and as a consequence, the output power of the electric motor
  • The diameter of the cage is an important parameter, t.к. between stator and rotor frames is the minimum calculated clearance for effective airflow from the manifold to the impeller.
  • Impeller diameter and design. the flow outlet is made through the holes in the gearbox housing, the profile of the impeller depends on it (mounting side, direction and design of blades), otherwise the cooling will be ineffective. A smaller diameter will not cool efficiently (and overheating is a “tool killer”), and a larger diameter is likely to jam in the housing. If all other parameters are the same, but the impeller is slightly larger, as a last resort, the excess can be removed mechanically.
  • The drive pinion or worm shaft seating. both diameter and length of the seating on the shaft are important, as well as, if provided by the design, the way of fixation under the key (segment or cylindrical size) or the mating slot of the pinion.

Construction of the rotor (armature) of angle grinder

Winding. metal rods (most often copper, but there is aluminum, which is significantly inferior), wrapped in rings in the grooves of the metal (toasted) frame with dielectric spacers, loops through the contact board (collector) in series connecting the different poles.

  • Bandage. a protective mesh made of elastic material that protects the winding from mechanical damage from large fragments, as well as creates additional whirls of air flow for better cooling.
  • Lacquer coating. heat resistant varnish provides increased resistance to high temperatures and prevents windings from shorting out.

What is the best manufacturer of angle grinders??

The highest quality angle grinders are made in Germany, USA, Japan. The market leaders in power grinders are rightly considered Hitachi (Japan), Bosch (Germany), Makita (Japan). The best proven and such brands as: DeWALT (USA), DWT (Switzerland), “Interskol” (Russia). Flattering reviews deserve and products manufacturer Sparky (Bulgaria). a pioneer in the production of angle grinder. As for popularity, the top three are Interskol, Bosch and Makita. angle grinder these manufacturers combine a low price and decent quality. For home especially often buy Interskol angle grinder. they are a little cheaper. Domestic brands of grinders markedly pulled up to the European and Japanese, and if it is impossible or unwilling to spend a large sum on the angle grinder, feel free to take the Russian angle grinder.

The top best grinders for home and professional use include devices that have earned a good reputation and positive feedback from consumers. Rating of the best grinders was created based on the opinions of users. We hope it will help you make the right choice.

KRÜGER KS-1300

The first place in the ranking of grinders for the home occupies a German machine, which features high quality build, safety in operation and high power of 1200 watts. The tool looks impressive and comes in a plastic carrying case for easy transportation and storage. Cutting discs 125 mm for cutting metal are included. The instruction is in Russian, and therefore problems with the use of the grinder will not arise. Among the additional options of the device. speed regulation, overload protection, accidental start lock plus a start button lock. There is a protective cover that increases the safety of using the tool. The engine is equipped with a cooling system, that is, the machine is designed for long-term continuous operation. According to user reviews, it is one of the best grinders by the ratio of quality, performance and price. Plus it’s light and handy.

“Took it for sanding a log cabin. I was looking for a model with adjustable speed, so I chose the Kruger grinder. Well, and its price is normal, moreover. Overall, the functionality is good. The machine coped with the task perfectly, I processed more than 200 cubic meters, and worked, interrupting only for lunch and sleep. The tool survived the job, the brushes are barely worn out, no backlash, humming, etc. I think it will last for years to come. A good technique, and it is not expensive either”.

Bort BWS-580

Probably the most inexpensive angle grinder of all the budget models that made the top. Power is low. only 580 W, so it is suitable for simple tasks in the home. In the complete set of the machine Bort there is a protective cover, the key to replace the disk nozzle. Works without humming. Grinds, performs simple cutting tasks. You don’t need much more from it.

“I did not know what angle grinder for the house is better to choose, on sale was a few, this model was advised by a consultant in the store. I took it for woodworking, the bath was building, and frankly, not particularly pleased. Overheats, if you work a long time. Have to turn it off. Well, it’s understandable, what I wanted. the power is small. For this price, on the other hand, the machine is quite robust.

BLACKDECKER G650

Angle grinder refers to the type of household, and has an average power of 650 watts. Reliability, quality, affordable price. not the only advantages of this angle grinder from the rating. It has also a high rotational speed of the disc and it is easy to change the disc. Weight is not too heavy, it has an additional handle for a secure grip. Of disadvantages. a high noise level.

“If you want to buy a good angle grinder for home use, you can pay attention to this option. It is a good tool for working on bars, that’s why I took it. But be aware that it is very noisy, and overheats if you work with it more than two hours. But it is very reliable. Second year in use”.

Zubr angle grinder-115-800 M3

Another one of the best grinders for the home with average power of 800 watts. Equipped with a power button lock, ergonomic design. Suitable for working at home or in the garage. Zubr technique has a small weight, additional two-position handle. There is no disc speed regulator. for many users it is a big minus.

“Little, not many functions. No speed regulator, the brushes to replace without consulting the offservice can not get. are the seals, and the price in the offservice. oh-ho. And if you replace it yourself, you can throw out the warranty. After two months the backlashes appeared, and after six months the rotor flew. I am not satisfied. Its price is not high, but it is not the best angle grinder on the market. You should have chosen more carefully.

Makita GA5030

A medium-powered tool with a comfortable handle and compact body. It is almost not warm when working. Comes with an extra handle, one disc for grinding and a protective cover. Vibration, according to users, is small. It is possible to use it with one hand. No additional options in the form of soft start or disk speed controller.

“It makes a lot of noise, I think even more than the claimed 96dB, you just freeze for a while if you work with it for a long time. Almost does not heat up when using it for a long time, that is a plus. I need to work on wood and I was disappointed that I can’t adjust the rpm of the sander. In my last one, the Interskol, you can. And wood is processed at low rpm. Frankly speaking, I think that the price is overpriced for such functionality. Though it is a very reliable tool”.

Metabo WEV 10-125 Quick

Machine with power of 1000 watts and a disk diameter of up to 125 mm. RPM is not as high as in previous grinders from the review. only 10500 rpm. But, according to customers, the tool copes well with the task of processing the materials. The process of working with the grinder is simplified by the two-position handle, spindle lock and start button. The machine has overload protection, disc speed control.

Checking and repairing the angle grinder armature

What the diligent homeowner wants to see in his “luggage” of power tools? To this question, everyone, without a second hesitation, will answer. a drill. And immediately add. and, of course, angle grinder! After all, it will help you cut metal, ceramic, brick, concrete, asphalt, stone, or wood; perform work on the arrangement of niches, arched and door openings. With the help of this power tool, you can clean surfaces from rust, scorch spatter and build-up; get rid of welds or simply polish metal to a shine. Angle grinder will become an indispensable assistant in other types of home repair.

What would not have been at the angle grinder (angle grinder) reliable design, during operation, some of the nodes and details fail. Breakage of an anchor, working in rather harsh conditions, is often the reason for the lack of normal functioning of an electric drive. In this article, the master plumber will consider how to repair or replace the armature of the angle grinder.

Anchor motor angle grinder is a current-conducting winding and a magnetic core, in which the shaft of rotation is pressed. It has a drive pinion at one end and a manifold with lamellae at the other. The magnet wire consists of grooves and soft plates coated with varnish to isolate it from each other.

Two conductors of the anchor winding are placed in the grooves according to a special scheme. Each conductor is one-half of a coil with the ends connected in pairs on the lamellae. The beginning of the first turn and the end of the last turn are in the same groove, so they are closed to one lamella.

When you buy a power tool, not many people think about the fact that someday it will break. Breakdowns can happen with any electric tool, regardless of price or manufacturer.

  • Breakage of conductors.
  • Intertwist faults.
  • Insulation breakdown on the ground is a winding short circuit to the metal rotor housing. Occurs due to destruction of insulation.
  • Collector terminal soldering.
  • Uneven wear and tear on the collector.

The main causes of breakdowns of chain saws, including their anchors, can be considered:

  • Mechanical wear. most often the brushes suffer.
  • Failure to maintain “nameplate” operating conditions. Armature and stator.
  • Overloads and mains voltage peaks. stator and rotor.
  • Failure of small parts. bearings, clips, nuts, washers, etc.
  • Dropping, knocking or other carelessness on the angle grinder. body breakage.
  • Lack of preventive cleaning. gearbox malfunctions or breakage of the on/off button./off.

If the armature is defective, the motor overheats, the winding insulation melts and the turns are short-circuited. Solder the contacts that connect the armature winding to the collector plates. The power supply stops and the engine stops working.

The scope of repair work allows you to determine the competent diagnosis of damage to the rotor. The specifics of the formation of defects, which most appear at overheating of the angle grinder during prolonged work at high loads, allows you to determine them visually.

Standard diagnostics involves visual analysis of the device. It is necessary to analyze the integrity of the wire and the current flow to the collector of the motor. If the power supply is normal, you should inspect the angle grinder from the inside. To disassemble the device is not very difficult. It is best to take a picture of the location of the main modules of the device during disassembly. After disassembly, conduct a visual inspection of the anchor for such properties:

When you buy a power tool, you never imagine that it will break down one day. Breakdowns occur with any electric tool, regardless of price and manufacturer’s firm.

  • Breakage of conductors.
  • Intertwist short circuit.
  • Ground insulation breakdown is the winding shorted to the metal body of the rotor. Occurs due to insulation failure.
  • Collector leads unsoldered.
  • Uneven wear and tear of the collector.

The main causes of breakdowns in bolt-type lathes, including their anchors, can be considered:

  • Mechanical wear and tear. most often the brushes suffer.
  • Failure to maintain the “nameplate” operating mode. armature and stator.
  • Overloads and power surges. stator and rotor.
  • Failure of small parts. bearings, retainers, nuts, washers, etc.
  • Dropping, knocks and other careless attitude to the angle grinder. breakage of the housing.
  • Absence of preventive cleaning. gearbox malfunctions or breakage of the on/off button./off.

If the armature is defective, the motor overheats, the winding insulation melts and the turns are short-circuited. The contacts connecting the armature winding to the collector plates are unsoldered. Current flow stops and motor stops running.

How to check the serviceability and perform the repair of the armature of the angle grinder with your own hands, step by step instructions, video

As Shakespeare said, “Nothing lasts forever under the moon. Household appliances, alas, are no exception. It happens that even the most reliable mechanism fails. And you should be prepared to meet this fact without panic, with the firm belief that there is no such thing as a hopeless situation. How the angle grinder is designed, what are the possible malfunctions, how to check the motor armature, determine the cause of failure and troubleshooting? Knowledge of the device of the main nodes of the power tool will allow the master with his own hands to diagnose and repair the angle grinder.

Features of the asynchronous motor of angle grinder

Almost all appliances used in the home, is used asynchronous electric motor. An important advantage of this type of motor is that when you change the load on it, the speed does not change. That means that if you cut through stone with a household angle grinder over a long period of time without stopping, you will not notice any outward signs of motor overload. The speed of the disc will be constant, the sound will be monotonous. Only the temperature will change, but you may not even notice it, if you have gloves on.

Asynchronous motor manifold is sensitive to overheating

If you’re not careful, the advantage can turn into a disadvantage. Asynchronous motors are very sensitive to overheating, a significant excess of operating temperature entails melting of the insulation on the rotor windings. At first the motor will run intermittently and then, after a short circuit, the motor will stop completely. If you overheat the angle grinder motor a few times, it is likely that the armature will melt. In addition, the high temperature causes soldering of the contacts that connect the primary winding wires to the collector, which leads to an interruption of the electric current flow.

How to determine if the angle grinder armature is defective

Signs of angle grinder armature failure are: increased sparking of brushes on the motor collector, vibration of the motor at low speeds, rotation of the working shaft in different directions. If these symptoms are present, you should stop working with the tool. it is dangerous. Suspicions can be easily checked with simple tests.

Visual inspection from the outside

Troubleshooting should begin with a visual inspection of the angle grinder:

  • Perform a general inspection of the tool.
  • Pay attention to the integrity of the power cord, the presence of voltage in the socket.
  • Using the voltage indicator, check that the current is flowing to the motor collector and the start button.

Inspect the inside of the appliance

If everything is all right with the power supply, but the angle grinder doesn’t work, you’ll have to open up the housing to get access to the motor. Disassembly is generally not difficult. But it is necessary to adhere to simple rules that will avoid trouble during reassembly:

  • Always disconnect the armature from the mains before disassembling.
  • Remove the operating disk and protective guard from the spindle.
  • Open the case in a well-lit place, on a clean table surface.
  • Memorize the location of all parts and assemblies before disassembly. It is a good idea to make a diagram or take a picture of the internal construction of the appliance.
  • Store screws and fastening screws in a separate location so that they do not get lost.

It’s best to inspect the motor under bright light so that all the fine details are clearly distinguishable. The anchor should rotate freely around its axis, properly functioning bearings should not make a sound during operation. There must be no sign of burned-out wires on the armature and the circuit windings must be intact, without rips. You can smell the rotor. If there is a short circuit between the cores, the insulating varnish will burn up and give off a lingering specific smell. But this diagnosis requires a certain amount of experience.

Check circuits with a tester

If a visual inspection does not yield obvious results, it is advisable to continue the examination with a multimeter. Having set the toggle switch to the ohmmeter position (200 Ohm range), it is necessary to “probe” the two neighboring lamellae of the armature with two feelers. If the resistance on all turns is the same, it means that the coils are serviceable. If in any pair of the tester shows a different resistance or breakage of the circuit, there is a fault in the coil.

Check the integrity of the coils with a multimeter in resistance measurement mode

A wire break can occur between the winding and the core. You should carefully inspect the connection points between the coils and the collector blades at the bottom of the armature, visually check the soldered contacts.

Checking contacts with a light bulb

If there is no tester, you can get out of the situation with the help of simple 12 volt bulb. Any power is possible, with an optimum rating of 30-40 watts. The voltage from the battery of 12 volts should be applied to the plug of the angle grinder, inserting a light bulb in the gap of one wire. If the armature is working, if you rotate the spindle by hand, the light should burn without changing the brightness. If the filament changes, that’s a sure sign of an inter-turn short circuit.

If the bulb does not light, it could indicate the following:

rotor, angle, grinder, much, weight
  • The brushes may be stuck in an inoperative position. The retaining spring has failed.
  • There is a break in the power supply circuit.
  • A short circuit or tear in the stator winding has occurred.

There are other ways of diagnostics, but they require more complex equipment that is not usually used at home. An experienced technician will determine the breakage with a high degree of accuracy, using a “puncher” or the simplest transformer with a cut toroidal core and a single primary winding.

In what cases you can save the anchor and restore it with your own hands

If the damage to the armature is established with guaranteed accuracy, the part must be removed from the electric motor. Dismantle the motor must be carried out with extreme care, first removing the brushes and disconnecting the power terminals. The rotor is removed along with the supporting bearings and the motor cooling impeller, they form a single whole with it.

Design and principle of operation of the angle grinder

Today, almost every home craftsman has an angle grinder in his possession. Nevertheless, many people do not know why it is so called, and what functions this tool can perform, in addition to the usual cutting. In this article, the master plumber will disassemble the device and principle of operation of the angle grinder.

Everyone familiar name. angle grinder. is so common that few people remember why it is so called. This tool is properly called an angle grinder (angle grinder).

Originally, it was designed for machining internal corners at the joints of two planes. The first samples of such machines were brought to the Soviet Union from Bulgaria, the country of that time, where they were produced. In the habit of the people tried to reduce the long and uncomfortable name. As a result, a new word has firmly come into use. angle grinder. But here on the package the correct name is indicated. angle grinder. Sometimes manufacturers use a variant of SMU (angle grinder) or MSHU.

Gradually all power tools, which externally resemble the prototype, began to be called in this way. Although there is a difference between them. For example, an angle grinder is often called a cut-off machine.

The external resemblance is undoubtedly present, but the cut-off machine is equipped with a pad so that the cut is directed perpendicular to the processed surface, which distinguishes it from the angle grinder.

The classic angle grinder is a hand-held power tool with an abrasive wheel. The main purpose of the angle grinder. processing joints of flat metal surfaces. But it can also be used for other applications. The basic wheel is excellent for cutting sheet metal, end trimming of pipes and fittings.

Simple replacement of the working wheel on a disk with sandpaper grinder turns into a polishing machine. Use the angle grinder in this capacity can be processed pipes for railing, flat or curved surfaces to a mirror shine.

In addition to working on metal, the angle grinder also cuts ceramic tiles. For this purpose, it is necessary to use a concrete disc as a working disc. The list of operations that can be performed with an angle grinder is very wide.

The design of angle grinders for all its types is almost identical, they all have the same components and assemblies. The main differences between the models are in the presence of additional components that perform different functions. For a complete understanding, let’s consider the device of the angle grinder and its main characteristics in more detail.

The device of an angle grinder is quite complex. What an angle grinder consists of, you can understand, looking at the figure below.

The design of the machine can be conditionally divided into two parts:
