Abstract
- This paper proposes a new partitioned stator hybrid-excited flux reversal machine with dual-PM (PS-HEFRDPMM), in which field windings are placed in the inner stator and PMs are employed on both the rotor and outer stator. By utilizing dual-PM excitation, the proposed PS-HEFRDPMM is able to introduce the bidirectional flux modulation effect to transmit high torque production. In addition, a good flux weakening capability can be obtained by using dc current to regulate air-gap magnetic field, which is beneficial to expand the speed range of machine. The machine topology, operating principle and design considerations of PS-HEFRDPMM are described, respectively. The electromagnetic characteristics of PS-HEFRDPMM under different excitation states are comprehensively analyzed using finite element method. The results show that the proposed PS-HEFRDPMM can provide the merits of high toque capability with low torque ripple, good over-load torque capability, high power factor and efficiency, as well as good flux weakening capability.
