This paper describes the high efficiency capability of multi-phase inverter-fed permanent magnet synchronous motors. In this type of motor, each armature winding is connected with an independent H-bridge inverter. The type of construction achieves a wide range of operation and high efficiency driving. Firstly, it is confirmed that the motor can expand the operating range by using winding reconfiguration. The inverter configurations are capable of changing their connections to different coil groups in the armature winding. To achieve high efficiency driving, a large torque production method and iron loss suppression method are proposed. With the proposed method of construction of the motor drive, the flux waveform in each stator tooth can observe and control in spite of the full-pitch distributed winding. The combination of controllable flux and arbitrary current excitation can generate a large output torque and reduce the iron loss. The simulation and experimental results show that the proposed method can significantly reduce the total loss.
