Abstract
A hybrid stator pole memory machine (HSP-MM) with direct current (DC) bias magnetization is developed in this paper. By introducing the concept of zero-sequence current magnetization, the DC magnetizing winding used in the traditional DC magnetizing MM is eliminated, which improves the utilization rate of internal machine space and the overall torque density. The re/demagnetization of low coercion force (LCF) permanent magnet by DC bias pulse enables HSP-MM to obtain the flexibility of flux regulation. The topology and adjustment flux principle of HSP-MM are depicted and addressed. The electromagnetic characteristics of the HSP-MM at different magnetization levels are analyzed and investigated, which demonstrates that the proposed machine has the good ability of flux regulation.
