直流无刷电机凭借其高效率、低噪音、长寿命等优点被广泛使用于各行各业。但是由于PWM控制驱动,造成轴电蚀损伤。本文结合电机内部结构,搭建直流无刷电机驱动电路模型和共模等效电路模型,解析轴电蚀产生机理,轴电压产生原因。同时,借助于共模等效电路模型,提出各种降低轴电压改善方案,利用Matlab/Simulink软件进行仿真和试验测试,比较各个方案的轴电压改善效果,为实际应用提供指导方向。

Brushless DC motor is widely used in more and more area with its high efficiency, low noise, long life and other advantages. However, as its PWM control drive, the bearing was damaged by electric erosion. In this paper, combined with the internal structure of the motor, Drive Circuit and equivalent circuit model for common mode of the BLDC motor was built to analyze the mechanism of bearing erosion and the cause of shaft voltage. Meanwhile, with common mode equivalent circuit model, various methods for reducing the shaft voltage are proposed, and the effectiveness was confirmed by both simulated and experimental results, which can provide guidance for practical application.
