    What should I do if the explosion-proof electric hoist motor does not rotate?


Description: The motor of the explosion-proof electric hoist is not running. What should we do when the explosion-proof electric hoist fails?

The motor of the explosion-proof electric hoist is not running. What should we do when the explosion-proof electric hoist fails? We all know that the motor of explosion-proof electric hoist or any kind of electric equipment is very important. The motor is equivalent to the human heart. The heart is the power in the human circulatory system. It is conceivable that if the human heart appears If there is a problem, then the entire human body will not be able to move and there may be other various problems. From this, it can be seen that if the motor fails and does not rotate or the motor is burned out in serious cases, the explosion-proof electric hoist will definitely be unusable, then we What should I do?
Explosion-proof electric hoist
First of all, we must first check which parts of the motor of the explosion-proof electric hoist have failed. Generally, the motor of the electric hoist has the following aspects:
1. The power supply voltage is too high, which greatly increases the heating of the copper core;
2. When the power supply voltage is too low and the electric hoist motor is hoisted for rated load operation, the voltage will cause the winding to heat up if the current is not large;
3. Repair and dismantle the windings, using improper thermal removal and burn copper core;
4. Rotor iron core phase rubbing; motor overload or frequent lifting;
5. Cage rotor broken bars; motor lacks phase, two-phase operation;
6. After rewinding, it is determined that the windings will not invade the paint;
7. Ambient temperature motor surface has a lot of dirt, or the ventilation is blocked;
8. Motor ventilation and fan failure, poor ventilation
All of the above reasons may cause the motor of the explosion-proof electric hoist to fail and burn out in serious cases, so we must do the inspection and maintenance before use, and clean it regularly, and operate the explosion-proof electric hoist in accordance with the correct and standardized operating procedures.
