摘要：

From the basic principle of flux-weakening speed-extension (FWSE) operation, effect of the d-axis inductance on the FWSE capability of permanent magnet machines was described. Such capability of 3-phase permanent magnet flux-switching motor (PMFSM) with different structures was studied, whilst the related structure design methodology was proposed. The influence of the rotor pole height and width on the d-axis inductance as well as on the flux-weakening capability was investigated, with both qualitative magnetic circuit analysis and quantitative finite element computation. The operation performance and flux-weakening capability of two types of PMFSM, i.e., those with 6/5-pole structure and 12/10-pole structure, was comparatively studied. It was shown that, under the limitation of the inverter capacity, the motor d-axis inductance and flux-weakening capability could be improved by optimizing the pole width, and both motor structures could provide good speed-extension capability, whilst the 6/5-pole structure was relatively better. The FWSE capability of the 6/5-pole PMFSM was also verified with experiments.
