现有文献中对磁通切换永磁（FSPM）电机的研究仅限于定子和转子极数的特定组合，即，12/10定子/转子极。本文分别采用有限元分析和集中参数磁路模型研究了定、转子极数对FSPM电机最优参数的影响。结果表明，虽然最大转矩的最佳转子极宽随转子极数而变化，但最佳转子极宽与转子极距之比几乎保持不变，即，~1/3.它还表明，12/13和12/14定子/转子极FSPM电机表现出比传统的12/10定子/转子极FSPM电机大~10%的电磁转矩。在12/14定转子极FSPM电机上进行的实验验证了分析的正确性。
The investigation on flux-switching permanent-magnet (FSPM) machines in existing papers has been restricted to a specific combination of stator and rotor pole numbers, viz., 12/10 stator/rotor poles. In this paper, the influence of stator and rotor pole numbers on the optimal parameters of the FSPM machines are investigated by the finite-element analysis and the lumped-parameter magnetic circuit model, respectively. It shows that, although the optimal rotor pole width for maximum torque varies with the rotor pole number, the optimized ratio of rotor pole width to the rotor pole pitch almost maintains constant, viz., ~1/3. It also shows that the 12/13 and 12/14 stator/rotor pole FSPM machines exhibit ~10% larger electromagnetic torque than the conventional 12/10 stator/rotor pole FSPM machine. The analyses are validated by an experiment made on a 12/14 stator/rotor pole FSPM machine.
