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.

具有直流偏置磁化能力的混合定子磁极记忆机的设计与研究

本文开发了一种具有直流 (DC) 偏置磁化的混合定子磁极记忆机 (HSP-MM)。通过引入零序电流充磁的概念，取消了传统直流充磁MM中使用的直流充磁绕组，提高了内部机器空间的利用率和整体转矩密度。通过直流偏置脉冲对低矫顽力 (LCF) 永磁体进行再/退磁，使 HSP-MM 获得磁通调节的灵活性。描述并解决了 HSP-MM 的拓扑和调整通量原理。对不同磁化强度下HSP-MM的电磁特性进行了分析和研究，表明所提出的电机具有良好的磁通调节能力。
