Research on Six-phase PMSM Two-motor Series-connected System Driven by Zero-sequence Harmonic Component

研究了一种基于零序谐波驱动的双Y移30°永磁同步电动机(PMSM)双电机串联系统,分析了零序谐波驱动串联系统的工作原理,建立了两台PMSM定子绕组串联联结的相序转换关系,给出了串联系统的独立解耦矢量控制方法,并通过电机变速、变载运行的仿真研究,验证了该串联系统的可行性。

The double Y shift 30° six-phase PMSM two-motor series-connected driven by zero-sequence har- monic component was researched. The working principle of the series-connected system based on zero-sequence har- monic component was analyzed. The phase-sequence conversing relation between two PMSM stator-windings was estab- lished. The decouple vector control strategy of this system was proposed. The simulating performances under variable speed and variable load were presented to validate the feasibility of the series-connected system.
