Abstract 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 Y-connected windings displaced by 30ℴ. 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 30ℴ.

Key words： Six-phase motor mathematical model decoupling harmonic currents closed loop control
