The reasons for the failure of energy-saving explosion-proof motor are:

(1) The power supply voltage is too low. If the power cable voltage drop is too high, replace the power cable with a thicker one. If the power supply voltage is too low, the power supply department shall solve the problem.

(2) The power supply voltage is too high. If the power supply voltage exceeds the standard, the power supply department shall solve the problem;

(3) Fixed and rotor core motorcycle wipe, if the bearing clearance exceeds the limit, replace the new bearing. If the rotating shaft is bent, straighten it. If the core is loose and deformed, handle the core;

(4) The winding surface is covered with dirt and foreign matter, and the motor is cleaned or cleaned;

(5) The motor is frequently started or positive or reverse too many times, reduce the number of motor starting, positive or reverse, or replace the appropriate motor;
