Design and Simulation of PM Brushless DC Motor Based on Simplorer and Maxwell

介绍了永磁无刷直流电动机基本原理,然后根据要求设计了一台9槽10极永磁无刷直流电动机,并用Simplorer和Maxwell联合对其进行了仿真,对电动机进行了空载、负载瞬态特性分析,验证了设计的合理性。最后试制样机,样机测试值与联合仿真值对比,验证了联合仿真的正确性。

This paper introduces the basic theories of the permanent magnet brushless DC motor; then designs a 9 slot 10 pole permanent magnet brushless DC motor. Simplorer and Maxwell are sued to carry out joint simulation for the motor. The transient characteristics of the motor in no--load and loaded condi- tions are analyzed to verify the rationality of the design. In the final prototype, the test value of the proto- type is compared with the joint simulation, and the correctness of the joint simulation is verified.
