摘　　要：本文以对称六相PMSM串联三相PMSM驱动系统为研究对象,按照一定的串联规则,实现了一台对称六相PMSM定子绕组和一台三相PMSM定子绕组的串联连接,推导了两电机串联系统的数学模型。两台电机由一台电压源型逆变器供电,可以实现对两台电机的独立的矢量控制。并以Matlab/simulink为工具,创建了两电机串联驱动系统矢量控制仿真模型,进行变速仿真研究,重点考虑了其中一台电机转速变化时,另外一台电机运行情况,进而验证了串联系统两电机解耦运行的可行性。The paper proposed a novel symmetrical six-phase PMSM two-motor drive system, which consis- ted of a six-phase PMSM series with a three-phase PMSM. And driven by a single inverter, this enabled full deeoupling vector control of the two machines. Detailed mathematical modeling of the system was presented. A simulation model with vector control was constructed by Matlab/simulink. The simulation results shows that the speed changing of one motor has no influences on the other motor, which validate the feasibility of independent control of the two machines.
