摘　　要：针对无刷双馈电机转子优化设计没有准确实现的方法,研究了最优点参数解耦法。对凸极磁障式转子进行了优化设计,得出了相应凸极磁障式转子对磁场调制能力最强的参数组合。通过与圆形片磁障式转子对比,得出了凸极磁障式转子输出电压幅值高、但对磁场调制能力弱的结论,也间接证明了最优点参数解耦法的可行性与正确性,为无刷双馈电机转子的开发提供了一种现实可行的优化方法。Aiming at the current problem of having no accurate and effective method in brushless doubly fed machines rotor design,decoupling method for optimal point parameters was put forward. The salient pole and magnetic barrier rotor was optimized and designed for the first time and the corresponding best parameters combination of salient pole and magnetic barrier rotor for magnetic field modulation ability was got. According to the comparison with magnetic barrier rotor,the conclusion was reached that salient pole and magnetic barrier has higher output voltage amplitude,but weaker magnetic field modulation ability,which also indirectly proved the feasibility and correctness of the decoupling method for optimal point parameters. It will provide a practical and feasible optimization method for the development of brushless doubly fed machines rotor.
