Nine, the explosion-proof motor quickly heats up after starting, even burning the winding
possible reason:
1. Winding turns, phase-to-phase shorts or grounding
2. Single-phase motor main and auxiliary windings are connected to each other incorrectly
3. The centrifugal switch contact cannot be disconnected after starting, and the auxiliary winding works for a long time and heats up.
Approach:
1. Check and repair the winding
2. Check correct wiring
3. Check and repair the centrifugal switch
Approach:
1. Check the power supply and wiring
2. Check the working machine and transmission part
3. Verify replacement of the motor
4. Check the power supply
5. Clear obstructions
6. Check the windings, repair
7. Plug-in and replace 9. After the start-up, the explosion-proof motor will heat up quickly and even burn the winding.
