What happens during the operation of the motor should stop the operation immediately

If the motor has the following conditions in operation, it must be immediately powered off for maintenance

1. Leakage of motor shell. If the motor shell leaks, it is generally the internal coil insulation is damaged, and it can no longer be used at this time, and the power supply should be removed and repaired as soon as possible;

2. The motor shell is seriously overheated. If the motor is overheated, it may be a short circuit in the coil winding, and it should be repaired or sent for repair;

3. The motor is smoky or has a burning smell. In this case, most of the coil windings are seriously burned, and the power should be cut off and repaired immediately;

4. Water ingress into the motor (except for submersible pumps). If the ordinary motor is flooded, it will cause a short circuit in the coil winding inside the motor, and if it is short-circuited, the winding will be burned out or leakage;

Note: When using the motor, if the voltage is too low or the current is not matched, the power should be cut off immediately and wait for the voltage to return to normal, if the voltage does not match, the winding will heat up, and the motor will not reach the normal working state.

If the motor has the following conditions in operation, it must be immediately powered off for maintenance

The first point is the leakage of the motor housing. If the motor shell leaks, it is generally the internal coil insulation is damaged, and it can no longer be used at this time, and the power supply should be removed and repaired as soon as possible;

The second point is that when a personal accident occurs, the motor emits smoke**, or the one-phase disconnection runs. There is a strong grinding sound inside the motor.

Thirdly, the motor is smoky or smells burnt. In this case, most of the coil windings are seriously burned, and the power should be cut off and repaired immediately;

Fourth, the commutator of the DC motor has a serious ring fire, the motor vibrates strongly and the bearing temperature rises rapidly or exceeds the allowable value, and the motor is flooded.

Note: When using the motor, if the voltage is too low or the current is not matched, the power should be cut off immediately and wait for the voltage to return to normal, if the voltage does not match, the winding will heat up, and the motor will not reach the normal working state.

The motor stops suddenly when it is working, and it starts again naturally after a few minutes, what is the reason.

When the motor is working, it stops suddenly, and starts naturally after a few minutes, what is the reason for you, the motor stops for a while, and the reason is as follows: 1 The power supply voltage of the motor is lower than the rated voltage, and the current value of the motor during operation exceeds the rated current value, which causes the electric hot to cause the action of the thermal protection lead protector, and the power supply voltage should be checked. 2. The overload operation of the motor also causes the thermal protector to act, and the load load should be reduced.

3. The stator winding of the motor has an inter-turn short-circuit fault, and the short-circuit current will also make the thermal protector or air open action, etc., and detect the motor winding. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

Summary. Hello dear, sudden shutdown during motor operation can be caused by a variety of reasons, such as power failure, internal failure of the motor, overload protection, etc. If the motor stops suddenly during operation, the following should be noted:

1.Stop the power immediately** to avoid further damage to the motor or other equipment. 2.

Check if the motor is overheating, and if it is too hot you should wait for it to cool down before checking. 3.Check whether the power supply line and control circuit of the motor are normal, whether there is loose or short circuit, etc.

4.Check whether the bearings and mechanical parts of the motor are normal, whether they are stuck or damaged, etc. 5.

Check whether the protection device of the motor is triggered, such as overload protection, short circuit protection, etc. 6.If none of the above checks find any problems, you can try restarting the motor, but be on the safe side.

Check whether the bearings and mechanical parts of the motor are normal, whether they are stuck or damaged, etc. 5.Check whether the protection device of the electric bending machine is triggered by delay, such as overload protection, short circuit protection, etc.

6.If none of the above checks find any problems, you can try restarting the motor, but be on the safe side.

If you are not sure how to deal with the sudden shutdown of the motor, it is recommended that you contact a professional maintenance personnel for inspection and repair.

Situations in which the generator should be shut down immediately during operation: (1) The generator and exciter vibrate strongly and exceed the limit value. (2) When endangering personal safety.

3) Smoke and fire inside the generator exciter or hydrogen inside the generator**. (4) When the generator, main transformer, high-voltage plant transformer and excitation system fail, and the protection device refuses to move. (5) Serious water leakage of generator wire rods, which endangers the operation of the equipment.

6) The transformer used in the main transformer or high-voltage plant catches fire. (7) When the purity of hydrogen in the generator decreases rapidly and is below 90%, or the hydrogen should seriously decline below the following. (8) The sealing oil system is faulty and cannot be maintained during operation.

Low oil pressure, overspeed, abnormal power generation voltage, abnormal sound of the unit (such as firing guns, knocking on cylinders).

Abnormal sound, smoke, odor, fire.
