Design and Analysis of a Novel Hybrid Excitation Flux Reversal Machine
Keywords:FEA, flux-reverse machine, GA, hybrid excitation, multi-objective optimization
A novel hybrid excitation flux reversal machine (HEFRM) is developed. The machine has a simple reluctance rotor and a stator, which has both an ac armature winding and a dc field winding. The core on the surface of the pole arc at the centerline of the stator pole and the core on the outer surface of the stator yoke each have a slot along the rotating axis, where the field windings are placed. A permanent magnet (PM) with opposite polarity is placed respectively on each side of a slot in the same stator pole. In this paper, the working principle of the new HEFRM is introduced, the influence of magnetic pole parameters and armature parameters on motor performance are also analyzed, and genetic algorithm (GA) is used for multi-objective optimization of the torque characteristics. Finally, the HEFRM prototype is built, and its theoretical correctness is verified by the finite element analysis (FEA).
