摘要：
In order to improve the operation efficiency at light load, an active phase-deficient method for a nine-phase flux switching permanent magnet (FSPM) motor is proposed in this paper. Namely, this method can activate corresponding winding group in accordance with various power conditions, to obtain the maximum efficiency under different winding combinations. In addition, the analytical loss models of the nine-phase FSPM motor and converter are built, and then the optimum winding work principle is discussed according to the power consumption. On this basis, the harmonic current components are accurately calculated, and the control block of active phase-deficient operation is designed. Finally, two switch modes (direct and fault-tolerant) are evaluated according to the optimum winding switch sequence. The simulation and experimental results verify the proposed control strategy. © 2019, Electrical Technology Press Co. Ltd. All right reserved.
