Almost everyone House master has among the tools a homemade emery from an electric motor. With it, you can sharpen various things needed in everyday life. You can, of course, buy such emery in the store. However, its cost is often very high. Therefore, craftsmen make homemade emery.

To make emery, you will need an asynchronous motor from the Soviet washing machine.

For such a device, it is very important to choose the right motor. Special nozzles are mounted on its shaft, which clamp the emery wheel.

How to choose the right motor for the device

In Soviet times, a lot of models of washing machines were produced. They were equipped with powerful engines with reverse. In addition, such a washing machine had a switch equipped with a starter.

The most difficult thing in arranging homemade emery, when such an electric motor is installed, is the process of attaching an abrasive stone to the axis. The shaft of the electric motor in most cases has no thread, the diameter of the hole in the stone often does not match the diameter of the shaft.

To solve this problem, you need to carve a special part. It must compensate for this disproportion. For the manufacture of homemade emery, it is necessary to plan the future dimensions of such a part. Most often, homemade emery is made using an asynchronous electric motor.

In order for the emery to have high performance, the engine must develop 3000 revolutions. If this number is much higher, then the grindstone may break. Therefore, in order to prevent the possibility of such a breakdown, an electric motor developing 1500 revolutions is used for the house. For an electric motor with 3000 rpm, it is necessary to use a stone of high strength. It must be fastened with a very high quality and reliable flange. Most often, high speeds are needed for polishing products. On such devices, sharpening occurs very rarely.

When done, you do not need to install a powerful electric motor. Professionals recommend using a 400W motor power for a stationary grinder. To work in the garage, the power of the electric motor is not more than 200 watts. This is exactly what the washing machine was equipped with. One of its positive qualities is low speed.

The main goal of the work

Before making emery, it is necessary to clearly understand the future direction of its operation. Usually homemade emery has the ability to change the direction of rotation of the rotor. The Soviet washing machine was supplied asynchronous motor. This allowed, when connecting certain windings, to change the rotation of the axis. Sometimes the motor has four outputs specifically for changing the rotation of the rotor.

To find out the desired direction of rotation, the tester determines:

• working winding;
• starting winding.

The resistance index of the working winding in most cases does not exceed 12 ohms, for the starting winding it reaches 30 ohms. The working winding is connected to the mains. one end starting winding connected to the output of the coil, its other end must be touched to the second output of the winding, and after touching it, immediately discard it. Usually, a special relay is used for such an operation.

Thus, the direction of rotation of the emery is determined. If the winding leads are reversed, the motor will start to rotate in the opposite direction. Sometimes they do not put a starting coil. To get started, you just need to spin the grindstone, the grindstone will start working.

Turning work: features

To be able to fix the stone on the axis of the engine, it is necessary to machine a special flange.

This work is done on lathe. A drawing is preliminarily made, where it is necessary to indicate:

• abrasive diameter, its inner hole;
• motor axis diameter.

In addition, a flange for the motor shaft is also machined directly on the machine. It is put on the axle, securely fastened with a bolted connection, and a nut with a left-hand thread is installed.

The threading of the nut, the thread of the flange directly depends on which direction the rotation of the motor shaft will be directed. For clockwise rotation, a left-hand thread is cut, for opposite rotation, a right-hand thread is cut.

When the desktop emery is turned on, spontaneous tightening of the nut will begin to occur. This nuance must be taken into account. If the nut begins to unwind, the abrasive stone may simply fly off during operation. This is very dangerous, because possible serious injury.

If you decide not to buy a grinding machine, but to make it yourself using your engine, then you will need the services of a turner. Manufacturing, and not buying, is very often justified for several reasons: it turns out cheaper, it turns out much better, it’s no secret that the stone sold in the grinding machines sold in stores happens to hit mercilessly. Eliminating the beating of a factory grindstone is no easier than making a good machine.

We manufacture two types of machines:

• The stone is installed through the nozzle on the engine. Advantage - simplicity, disadvantage - you can install only one stone. You can install two stones, but by removing the engine cooling system. The impeller has to be removed.
• An axle with two stones at the ends and a pulley in the middle is driven by a separate motor. With this option, the beating of stones is minimal, the engine is perfectly cooled and does not become clogged with abrasive particles. Such a system works many times longer. Such a scheme is suitable for working with grinding and cutting diamond tools both with water supply and without water.

We can manufacture a grinding or cutting machine, completing it with everything you need. We can also use your components: motor, bearings, metal blanks, belts, etc. to manufacture a machine according to your drawings and wishes, which will be very much cheaper, but no worse in quality.

If you need to make nozzles for hand power tools: drill, dremel, grinders, we will help you. The precision of our machines is quite sufficient so that the nozzle does not vibrate even at a speed of 20,000 revolutions.

Do you have an old washing machine that is beyond repair? Do not rush to get rid of it, from this article you will learn how to make emery from the engine of a washing machine.

A homemade sharpener from a motor is always useful on the farm and for household needs. Moreover, industrial emery is expensive in stores, while a grinder from an automatic washing machine will cost free.

An emery machine is useful for such work:

• Restoration of the cutting qualities of the drill. In order not to buy new drills, you need to know how to sharpen old ones. While working with a drill, the drill gets very hot, which is why it constantly becomes dull. Having sharpened it on the machine, you can use it many more times.
• Sharpening of knives, scissors, shovels and other tools. Thanks to homemade machine from the washing engine, your knives will always be sharpened, and the scissors will cut perfectly. This does not require much effort.
• If you replace the emery wheel with a polishing wheel, you can easily process products and parts.

Using the motor from the washing machine, you can make a sharpening machine with your own hands. To do this, you will have to buy only one part - an emery wheel. All other components are in the motor.

Which engine is suitable for making emery

Wondering which engine to use? You can use any motor from a washing machine, even the Vyatka, Riga or Volga brands. The main thing is that it has enough power.

For normal operation grinder, enough power of 100-200 W, with 1000-1500 rpm. For particularly large parts, a 400 W motor is suitable. But if the engine speed reaches 3000 rpm, it needs to be adjusted or a very strong disk installed.

What you need to create emery from a washing machine motor

To make a simple grinder you will need:

• washing machine engine;
• flange;
• sleeve;
• nozzle on the electric motor (emery wheel);
• casing for protection;
• support;
• starting device.

When buying, it is better to choose a product with two circles: a finishing and a rough version.

You also need to make an adapter with a flange. Since the size of the shaft does not match the hole of the grindstone, an adapter must be made. You can perform it on a lathe, having previously determined the dimensions and completed the drawing. On the diagram, it is necessary to note the diameter of the shaft and the emery hole.

The flange on the shaft can be made independently. A piece of pipe with a diameter of 32 mm, no more than 200 mm in length, will do. It should ideally sit on the motor shaft. On one side of the flange, a thread is made, the direction of which depends on the direction of movement of the shaft. When sent to the engine, the other end of the flange is heated and pressed.

Be sure to secure the flange after installation. This can be done by welding or bolting by drilling a flange with a shaft.

The adapter from the shaft is ready. It remains to install the element for sharpening the cutters.

DIY steps for creating emery from a washing machine engine

For homemade device use a belt driven motor.

It remains to correctly assemble the device. After installing the flange, put a nut with a washer on the shaft, then a large emery wheel and again a nut with a washer.

Motor connection

How to connect the engine from the washing machine:

• Using a tester-multimeter, look for tachogenerator wires that show a resistance of 70 ohms (usually they white color). We will not use them.
• There are four wires left. Using a multimeter, you need to determine the paired wires.
• Connect the wires leading to the stator and to the electric brushes. The remaining wires must be connected to the wire and plug at the end, and then connected to the network.
• Connection points must be isolated.

Immediately after connecting, the motor for homemade emery will start working, and you will be able to evaluate the functionality of the device.

Connecting the electric motor of Soviet-made washing machines differs from the previous version.

• Here you will find only 4 wires. Need to find a couple.
• Take a multimeter, measure the readings of each of the wires. You need paired wires with less resistance that go to the working winding.
• Connect these wires to the plug and connect to the mains.
• Now you need to make a launcher. You can use any button, for example, from a door lock. Connect one wire coming from the button to the starting wire (PO), and the other to the working wire (OB).

The motor is now connected. But before starting work, you need to thoroughly fix the machine in order to avoid an emergency.

How to put an emery machine and make protection

How to fix the emery machine and put protection on it? You can bolt it to a workbench.

To do this, use the bracket that is in the washing machine. To reduce vibration during operation, rubber gaskets are put on the corner, which can be made from a piece of hose.

If the device is installed on a wooden workbench, cover it with a sheet of metal on top to avoid fire.

For your own protection, when using the machine, install a metal arc over the disc. You can also enhance the protection by attaching 5 mm thick Plexiglas to the pendants. The glass can be raised and lowered by means of suspension brackets.

Making your own grinder is easy. The main thing is to properly fix and connect it. Also follow the safety rules at work, use protective glasses and special clothing.
