A Novel Flux Concentrated Stator Consequent-Pole Permanent Magnet Machine With Nonuniform Stator Modulation Teeth

This article presents a novel flux concentrated stator consequent-pole permanent magnet (FCSCPM) machine with nonuniform stator modulation teeth (NSMT) design, which provides a relative lower magnetic reluctance circuit for low-order working harmonics and hence resulting a higher torque capability. To confirm the merits of the proposed design, the conventional and symmetrical stator modulation teeth (SSMT) FCSCPM machines are selected and compared by finite element (FE) analysis. The simulated results show that the proposed design exhibits a higher torque capability, better field-weakening ability, and a relatively larger high-efficiency (≥90%) region than conventional and SSMT cases. It validates the feasibility of the proposed design with performance improvement.
