Brushless motor will inevitably have various problems after long-term use. If the motor is short-circuited, how should we solve it? Xiaobian will give you a brief introduction!
The first yi, there is an open circuit phenomenon in the front of the brushless motor, the motor should be connected, the labor is welded, and then wrapped with insulating material, covered with insulating tube, wrapped and dried;
Secondly, the phenomenon of cage breakage of the motor cage rotor can be repaired by welding method, cold welding method or belt replacement method;
Third, the breakpoint in the slot, the breakpoint can be found by the group elimination method, and the breakpoint is connected in the winding, and the insulation is checked before use;
Fourth, if the winding is seriously burnt due to daytime, phase-to-phase short circuit and grounding, etc., the new winding should be replaced.
Xiao Bian reminds: When repairing the brushless motor, it should be combined with the local actual situation, open up the idea, gradually analyze, and eliminate one by one until the real cause of the fault is found.
