本文通过有限元分析研究了4/2单相FSPM电机的启动转矩，并进行了实验验证。结果表明，转子极弧可以显着影响电磁扭矩和启动能力，因为它还影响齿槽扭矩的幅度和波形，从而影响稳定转子静止位置的数量和角度位置。因此，转子极弧是必须优化的关键设计参数。 2D 和 3D 有限元分析均表明，80 度的极弧可产生最有利的扭矩-位移特性，这一点已通过实验得到证实。
In this paper, the starting torque of the 4/2 single-phase FSPM motor is investigated by finite element analysis, and validated experimentally. It is shown that the rotor pole-arc can significantly affect the electromagnetic torque and starting capability, since it also affects the amplitude and waveform of the cogging torque, and, therefore, the number and angular location of stable rotor rest positions. Thus, the rotor pole-arc is a key design parameter which must be optimized. Both 2D and 3D finite element analyses show that a pole-arc of 80deg results in the most favourable torque-displacement characteristic, as has been confirmed experimentally.
