摘要
In this paper, a new hybrid-excited doubly salient dual-PM machine (HE-DSDPMM) with dc-biased sinusoidal current is proposed. The HE-DSDPMM employs yoke-PM and slot-PM simultaneously to introduce parallel dual-PM flux to increase the torque production. In addition, the dc-biased sinusoidal current is used in HE-DSDPMM to achieve the flux regulation without field windings. The configuration and working principle of HE-DSDPMM are first described. Subsequently, the design considerations of HE-DSDPMM are discussed, which mainly focus on studying the influence of key design parameters on torque characteristics. Finally, the electromagnetic performances of HE-DSDPMM are analyzed comprehensively using finite element method. The predicted results indicate that HE-DSDPMM can offer the advantages of high torque capability with low torque ripple, good over-load torque capability, as well as flexible flux regulation capability.
