Comprehensive Armature Reaction Modeling and Flux Weakening Optimization of a Surface Permanent Magnet Vernier Motor

Surface permanent magnet vernier motors (SPMVMs) possess the potential for direct-drive applications due to feature of high torque density. This paper presents a deep investigation into armature reaction modeling and semi-analytical optimization framework considering constant power speed range (CPSR) in flux weakening region SPMVM. The new model can identify air gap density each harmonic component linkage accurately, by conducting harmonics analysis, slot leakage computation slotting effect evaluation, permitting calculate inductance. Then, results from those obtained finite element analysis (FEA) at rated operating point together are applied comprehensive motor developed SPMVMs. is able reflect performance metrics over entire range, with density, factor CPSR as objectives. Finally, prototype designed according trade-offs objectives fabricated confirm validity framework.
