摘要
利用Ansoft软件分析计算了空载和负载时,永磁无刷直流电动机(BLDCM)的磁场分布、静态特性,并在此基础上讨论了几种减小此种电机转矩脉动的方法。同时用Ansoft/transient软件对电机起动和突然改变负载时的动态特性进行了仿真。静动态特性的分析结果对设计、使用该种电机,特别是对电机控制系统的设计有参考价值。
Magnet field distribution and static characteristic of permanent-magnet brushless dc motor（BLDCM） at no-load and load are analyzed and calculated by Ansoft software and various methods of reducing torque pulsation of this kind of motor are discussed on this basis. In the meantime, dynamic state characteristic of motor during starting and transient load changing are simulated by Ansoft/transient software. Analytic resuits can be referred for design and using of this kind of motor in particular for design of controlling system.
