A Novel Sub-Harmonic Synchronous Machine Using Three-Layer Winding Topology

This paper proposes a novel brushless synchronous machine topology that utilizes stator sub-harmonic magnetomotive force (MMF) for desirable operation. The MMF component is used in this one fourth of the fundamental component, whereas, previous practices, it was half. To achieve operation, uses unique winding configuration two sets balanced 3-phase wound 3 layers. For rotor, additional placed to induce excitation. Unlike its predecessors, maximum allowable space house conductors all slots. implement topology, 8-pole, 48-slot model has been designed. A 2-D finite element analysis (FEA) simulate and validate performance as motor. proposed shows better average torque than existing rotor topologies.
