| 摘 要： | 为抑制开关磁阻电机(SRM)转矩脉动,提出了一种新型定子极面结构,将传统均匀气隙结构改成两段式的非均匀气隙结构。以一台11 kW、1 000 r/min、12/8极SRM为例,通过建立二维场路耦合时步有限元模型,对此类结构进行了验证与优化。结果表明:此类结构能够在保证电机效率基本不变的情况下,有效抑制转矩脉动,为进一步提升SRM的设计与运行水平,提供了有益的参考。

| Abstract: | In order to suppress the torque ripple in the switched reluctance motor, a new stator pole shape was proposed. It changed the traditional uniform air gap into nonuniform air gap of two sections. An 11 kW, 1 000 r/min, 12/8 SRM as the prototype, the structure was validated and optimized through establishing the twodimensional fieldcircuit coupled timestepping finite element model. The results showed that the structure could reduce the torque ripple effectively with ensuring the efficiency of the motor unchanged. A useful reference to promote the level of design and operation of switched reluctance motor was provided. |
