Brushless motor controller will appear all sorts of problems after using for a long time, if the motor controller circuit, we should be how to solve and give you a brief introduction of small make up! 1, the front of the brushless motor controller appear open circuit phenomenon, motor controller can good, good welding labor, then wrapped with insulating materials, set on the insulation tube, wound, drying; 2, the cage rotor of motor controller is broken cage phenomenon, can use welding, cold welding repair or replacement method; 3, trough the breakpoint, the available set of eliminating method to find the breakpoint, and breakpoints in the winding connection is good, qualified before use inspection insulation; 4, because the turn-to-turn, interphase short circuit and grounding severely burned to causes such as winding, a new winding should be replaced. Small make up remind: when repair brushless motor controller, should be combined with local actual situation, open thinking, analysis step by step, one by one, until find out the real reason for failure.
