Halbach结构在空间环境电机设计中的应用

Application of Halbach Structure on Motor Design for Space Environment

提出了一种基于Halbach结构的永磁电机优化设计方法,电机性能更优、质量更轻,电机空载反电动势畸变率降低了24%,输出转矩提高了1.5%,转矩波动降低了23.8%,转子质量减少了34.3%,通过样机验证了该设计方法的正确性。

An optimal design method of permanent magnet motor based on Halbach structure was proposed,which made the motor have better performance and lighter weight,the no-load back EMF distortion rate of the motor was reduced by 24%,the output torque was increased by 1.5%,the torque fluctuation was reduced by 23.8%,and the rotor weight was reduced by 34.3%.The correctness of the design method was verified by a prototype.
