N2 - In this paper, a novel dual-permanent-magnet motor (DPMM) with hybrid-stator-teeth structure is proposed. With hybrid stator teeth, the number of flux modulation poles can be more flexible and the relation between modulation poles and stator slots can be extended. A general slot/pole combination equation for this kind of DPMM is concluded. The conventional slot/pole combination between stator slots and rotor poles of the DPMM can be broken and more flexible slot/pole combination can be realized. One model with hybrid stator teeth based on the concluded equation is taken as an example and its performances, including airgap flux density, output torque, torque ripple, torque/PM volume, loss distribution, and efficiency, are analyzed in detail. Moreover, a traditional split teeth DPMM with the same stator slots and winding pole pairs will be optimized and the performances of the proposed motor and the traditional one will be compared. The results show that the hybrid teeth motor can maintain comparable performances to the split tooth motor with reduced permanent magnet usage. The effectiveness of the motor design is verified through simulation and comparative study.
