What causes the motor winding to ground?

Release time:

2024-01-03


(1) Asynchronous motors are overloaded for a long time, causing friction between the stator and rotor (sweeping the bore).

(2) The insulation of the winding is affected by moisture, which reduces the insulation performance and leads to grounding (commonly known as "shell collision") faults.

(3) When replacing the stator winding, the insulation slot is not properly padded or damaged.

(4) The winding end is too long and collides with the end cover
