摘　　要：基于空间矢量解耦方法,建立绕组正弦和非正弦分布的双Y移30°六相永磁同步电机旋转坐标系下数学模型;为了减小谐波子空间电流,研究了谐波电流闭环控制和谐波电压开环控制两种控制方法,得出两种控制方式下相电流FFT分析结果。仿真和实验结果表明:谐波电流闭环控制方式对绕组正弦和非正弦两种电机具有更好的电流谐波控制效果,可以减小系统损耗,该方法更适合于双Y移30°六相永磁同步电机的控制。Based on the method of space vector decoupling, mathematical models are established in rotating coordinate system separately for six-phase permanent magnet synchronous motors, which are manufactured with two sinusoidal or non-sinusoidal -connected windings displaced by 30° . In order to reduce the currents in harmonic subspace, methods of harmonic current closed-loop control and harmonic voltage open-loop control are studied respectively, and FFT analyzed results of phase currents are obtained. Simulation and experimental results imply that harmonic current closed-loop control mode has a better performance in limiting harmonic currents of both sinusoidal and non-sinusoidal winding motors, and the system losses can also be reduced. This control method is more suitable for control of six-phase permanent magnet synchronous motor with two Y-connected windings displaced by 30° .
