1 The power supply voltage is too high, so that the iron core heat is greatly increased;
2 The power supply voltage is too low, the motor is operated with the rated load, and the current is too large to make the winding heat;
3 When repairing and removing the winding, use the thermal disassembly method improperly to burn the iron core;
4 fixed rotor core rubbing;
5 motor overload or frequent start;
6 cage rotor broken bars;
7 The motor is out of phase and the two phases are running;
8 rewinding is not sufficient for the winding dipping paint;
9 high ambient temperature, the motor surface has a lot of dirt, or the air duct is blocked;
10 motor fan failure, poor ventilation; stator winding failure (phase-to-phase, inter-turn short circuit; internal connection of stator windings is wrong).
2. Troubleshooting
1 Reduce the power supply voltage (such as adjusting the power supply transformer tap), if the motor Y, Δ connection error caused, you should correct the connection method;
2 increase the power supply voltage or change the thick power supply wire;
3 overhaul the iron core to eliminate the fault;
4 eliminate the rubbing point (adjust the air gap or setback, car rotor);
5 load shedding; control start according to the specified number of times;
6 check and eliminate rotor winding faults;
7 resume three-phase operation;
8 using secondary dipping paint and vacuum dipping process;
9 cleaning the motor to improve the ambient temperature, using cooling measures;
10 Check and repair the fan, replace if necessary; repair the stator winding to eliminate the fault.
