Reasons for the failure of explosion-proof motors

(1) The power supply voltage is too low. If the voltage drop of the power cord is too large, replace the thicker power cord. If the power supply voltage is too low, it will be solved by the power supply department;
(2) The power supply voltage is too high. If the power supply voltage exceeds the standard, it will be solved by the power supply department;
(3) The stator and rotor iron cores rub, if the bearing clearance exceeds the limit, replace the new bearing. If the shaft is bent, straighten it. If the iron core is loose and deformed, deal with the iron core;
(4) The surface of the winding is covered with dirt and foreign objects, so clean or clean the motor;
(5) The motor starts frequently or the number of forward and reverse rotations is too many, reduce the number of motor starts and forward and reverse rotations, or replace the suitable motor;
When the operating environment of the motor is harsh and the working conditions are complex, it is very important to identify and take measures quickly when the motor runs abnormally. Before checking the fault, the power should be cut off. Routine inspection and maintenance are very important, so as to ensure the normal operation of the explosion-proof motor after maintenance and troubleshooting.
