Where the rotor is broken and repaired, it says that the rotor cannot be repaired?

The rotor is prone to reversing difficulties, high speeds, and various faults. Common faults include commutator damage, bearing damage, blade damage, brush wear, rotor winding burnout, etc.

1. The commutator is damaged.

The common faults of the commutator are the surface burning hole, the commutator flying out, the short circuit between the commutator and the commutator piece, the commutator is out of circle, the commutator is overworn, the mica sheet is protruding, and the commutator piece and the coil lead wire are virtually connected.

The commutator should be replaced if the commutator surface is burned into a hole, the commutator piece flies out, the short circuit between the commutator and the commutator piece, and the commutator is worn excessively, and the rotor winding also needs to be replaced.

For the fault of the commutator out of round, it can be continued to be used after processing with a horizontal lathe.

If the commutator piece and the coil cause a false connection, the fault point of the false connection can be washed, riveted or welded according to the situation. If the fault point cannot be found, the commutator can only be replaced, and the rotor winding also needs to be replaced.

If the mica sheet of the commutator is protruding, one side of the hacksaw strip with teeth can be sanded thin, and the mica can be lowered for a moment, and chamfered and grinded.

2. The bearing is damaged.

Bearing models commonly used in power tools are etc.

The common faults of bearings are excessive clearance, bearing fragmentation, running jackets, running inner jackets, locking, etc.

For faults such as excessive bearing clearance, bearing fragmentation, locking, etc., it is necessary to replace the bearing with a new one. For some running jackets, the gap is too large, you can pad the thin iron sheet (such as some iron beverage bottles can be used) or replace the casing. For some gaps that are not particularly large, they can be solved by applying AB all-purpose glue.

For some running inner sleeves, it can be solved by punching the pitting method on the reel.

3. The blades are damaged.

When the blade is broken, deformed and loose, the blade can be dismantled or replaced with a new one. For the deformation of iron blades, it can also be corrected with needle-nose pliers. For the loose between the blade and the shaft, it can also be coated with AB all-purpose glue to stick firmly.

4. Brush wear.

In general, when the length of the brush wears out to 1 3 of the original length, it should be replaced. If the brushes are too short, it is easy to burn the commutator and cause the rotor to be scrapped. The size of the brush is generally expressed in length, width and height, and the same grade should be used to replace it in addition to the same size.

In general, 2 brushes should be replaced at the same time.

If the motor rotor is damaged, the principle of repair is this, the squirrel cage rotor, the shaft damage can be solved by changing the shaft and re-balancing. If the rotor is "broken", it can only be scrapped. Wound rotor, no matter if it is damaged, it is not recommended to repair, the maintenance cost is high and it cannot be used after repair, and it needs to be updated.

It can be repaired, but it is time-consuming and laborious as replacing it with a new one.

Hello dear thought you found a simple fix for the rotor is broken1First of all, connect the rotor of the motor with a wire and the power supply, and check whether the power supply is stable; 2.If the power supply is normal, check whether the winding source on the rotor is damaged, if it is damaged, you need to replace it with a new land crack winding; 3.

If the windings on the rotor are well known, check the bearing to see if there is any looseness or damage, and if so, you need to replace the new bearing; 4.If the bearing is normal, you can try to apply a layer of grease to the rotor to see if you can restart the motor; 5.If none of the above methods can be repaired, you will need to replace it with a new rotor. Remember.

1. Check the rotor: check whether the rotor is damaged, if it is detected with wear and tear, fracture and other phenomena, it may be that the rotor itself is damaged. 2. Replace the rotor:

If the rotor is damaged, you can replace it with a new rotor wall to ensure the normal operation of the rotor. 3. Check the bearing: check the bearing, if the bearing is found to be damaged, you can replace the new bearing to ensure the normal operation of the rotor.

4. Check the number of variables and hail gearbox: check the gearbox, if you find that the oil film is thin or the oil hole is blocked, you can replace the gearbox oil to ensure the normal operation of the gearbox. 5. Check the cable:

Check the cable, and if you find that the cable is broken or the cover sail is broken, you can replace it with a new cable to ensure the proper operation of the rotor. 6. Check the transmission device: check the transmission device, if the transmission device is found to be abnormal, the transmission device can be replaced to ensure the normal operation of the rotor.

Summary. Hello, dear. Simple repair of broken rotor, check the wear of the bearing position, and verify the size; 2.

The bearing position is roughly ground as a whole, and the high point caused by the sintering of the bearing position is removed; 3.air test tooling; As the core component of the motor structure, the rotor shaft bears the size of the matching parts between the various components of the motor and the installation, and the rotor shaft is often subject to wear and impact in the process of work and maintenance, resulting in damage, once the wear will cause the whole motor to not run and affect the production. The rotor shaft of a crusher of a company has serious wear and tear failures, let's see how to easily complete the maintenance work.

I am a starter rotor, and the function of the starter rotor is to transmit the torque of the motor to the diesel engine crankshaft, as the pivot part of the middle leakage, and its components are a single missing front clutch and pinion.

Motor repairs include rotor repairs, but the reality is that the rotor damage rate is very small, whether it is a squirrel cage or a wound type.

Generally, the rotor should not be broken, once it is damaged, the general maintenance department can not be repaired without equipment. I have been repairing motors for 18 years and have never had a rotor being damaged.

The motor rotor is generally not damaged. If there are about two situations of damage: 1) the shaft of the motor is bent, and it will beat violently and cause vibration when rotating, because the speed of the motor is very fast, which is easy to cause fatigue fracture of the shaft!!

So it must be repaired. 2) The bearings at both ends of the rotor are worn, and after the bearings are installed, the radial clearance is large, which causes the shaft to run, the noise is very large, and it will also cause the bearing to be hot and overheated. This situation must also be repaired.

Of course, the vast majority of general motors are burned out by the coil, and the repair is aimed at this situation. However, if there are still mechanical problems to be repaired, the workload must increase a lot, and if it is sent outside for repair, the cost of repair will definitely increase.

Electric motor maintenance includes all contents, if there is a problem with the rotor, it must be dealt with.
