Solution to Short Circuit of Brushless Motor

Release:admin Visits:

Brushless motor will inevitably have various problems after long-term use. If the motor is short-circuit, how should we solve it? Let's give you a brief introduction.

First, there is open circuit phenomenon in the front of the brushless motor. The motor should be connected well, then wrapped with insulating material, covered with insulating pipe, wrapped well and dried.

Secondly, the broken cage of motor cage rotor can be repaired by welding method, cold welding method or belt replacement method.

Thirdly, breakpoints in grooves can be found by winding elimination method, and the breakpoints can be connected well in windings, and the insulation qualification can be checked before use.

Fourthly, if the windings are seriously burnt down due to inter-turn, inter-phase short circuit and grounding, new windings should be replaced.

Xiaobian reminds: when repairing brushless motor, we should combine the local actual situation, broaden our thinking, step by step analysis, eliminate one by one, until we find out the real cause of the fault.
