    Is the temperature of the motor too high during the hoisting of the explosion-proof electric chain hoist?


Description: Many users have encountered the phenomenon of excessive motor temperature during the use of explosion-proof chain electric hoists. In fact, it is normal for the motor to have a temperature when it is working, but if the temperature is too high or it is hot, it needs to be stopped for maintenance, resulting in the motor The reasons for the high temperature rise are summarized as follows:
Many users have encountered the phenomenon that the motor temperature is too high during the use of explosion-proof chain electric hoists . In fact, it is normal for the motor to have a temperature when it is working, but if the temperature is too high or it is hot, it needs to be stopped and repaired, which will cause the motor temperature to rise The reasons for the high level are summarized as follows:
Explosion-proof chain electric hoist
1. First check whether the explosion-proof chain electric hoist is overloaded. If the overloaded use will cause the motor to heat up, the motor will be burned if it is overloaded for a long time. The load must be reduced before it can start working again.
2. The motor is hot without overloading. It should be checked whether the motor shaft is damaged, and the bearing is also easy to heat the motor. In addition, it should also be checked whether the explosion-proof chain electric hoist motor works according to the design conditions. If not, it can also cause the motor to heat; During work, work strictly according to the motor working system.
3. When the motor is running, the brake clearance is too small and not completely disengaged, which will generate a large amount of frictional friction and heat, and this situation is quite an additional load, which reduces the speed of the motor, increases the current, causes the motor to heat, and increases the temperature of the motor. high. In this case, stop lifting and readjust the brake clearance.
In short, the temperature of the motor of the explosion-proof chain electric hoist is normal, but if the temperature is too high, we must pay attention to it and find the cause in time to avoid damage to the motor and affect the work progress.
