N2 - This paper proposes a novel stator spoke-type hybrid magnet memory machine (SST-HMMM)with flux-focusing hybrid magnets located between the adjacent stator poles. The proposed SST-HMMM is geometrically characterized as a simple doubly salient structure, and two sets of permanent magnets (PMs)with series-type circuit are employed to combine the high torque capability of high-coercive-force (HCF)PM, as well as wide magnetization state (MS)adjusting range of LCF PM. Meanwhile, the series hybrid magnet configuration permits beneficial unintentional demagnetization withstand capability. The machine structure and operating principle are introduced, respectively. In addition, a simplified magnetic circuit model is established to analytically optimize the magnet hybrid ratio. Then, the stator/rotor pole combinations are analyzed in order to select the optimal rotor case. The electromagnetic characteristics of the selected 6-stator-slot/7-rotor-pole structure are investigated, which confirms the feasibility of the proposed SST-HMMM design.
