对一则电梯制动器制动线圈放电回路故障的思考

Thinking About the Fault of the Discharge Circuit of the Brake Coil of Elevator Brake

针对某电梯制动器制动线圈放电回路存在过热和烧损的情况，分析了其产生的原因：给出了制动器放电回路的检验方法：仿真模拟了制动器制动的全过程，直观解释了制动器电流变化的过程。

Aiming at the overheating and burning situation of the elevator brake coil, the overheating and burning causes are analyzed. The test method of brake discharge circuit is given, the whole process of the brake is simulated, and the current change process of the brake circuit is explained,.
