摘要
论述了正弦波驱动电机系统中的经典型的轴承电流,讨论了逆变器驱动电机系统中的高频磁通产生的轴承电流,分析了环路型轴承电流产生的机理,并且在实验的基础上,得出了环路型轴承电流与共模耦合电流之间的关系,丰富和完善了电机轴承电流的研究内容.
The classical circulating bearing current is first reviewed to help understand how a flux linkage can induce bearing currents. The circulating bearing current generated by a high frequency flux in the inverter driving motor is discussed. This paper makes a theoretical analysis of the generation mechanisms of circulating bearing current; and describes the experimental findings, and states why the circulating bearing current should be related to a flux linkage produced by the common mode coupling current, and explains the relationship between the common mode coupling current and the circulating bearing current in induction motors.
