Brushless motor controller used for a long time after the hard to avoid can appear all sorts of problems, if the motor controller circuit, how should we solve it? Small make up to you to make a brief introduction of! 1. Break phenomenon appeared in the front of the brushless motor controller, motor controller shall be connected well, welding, package on insulating materials again, on insulating tube, tie is good, then drying; 2. Motor controller appear broken squirrel-cage rotor cage phenomenon, can use welding, cold connection or change the original repair; 3. Cut-off points within the tank, can be eliminated by grouping method to identify breakpoints, and broken in the winding connection is good, the only after they have passed the inspection of insulation used; 4. By reason of turn-to-turn, interphase short circuit and grounding caused winding badly burned, a new winding should be replaced. Small make up remind: the brushless motor controller for repair, should combine the local actual situation, open thinking, step by step analysis, ruled out one by one, until you find the real cause of the problem.
