多相电机 meaning in Chinese

polyphase machine

Based on finite element method ( fem ) , further study on permanent magnet linear synchronous motor ( pmlsm ) is presented in this thesis to improve the servo performance of the pmlsm , some measures for optimizing the air - gap magnet fields and a new method applying multiphase winding for eliminating the harmonics of the thrust are presented
本文以有限元方法为基础，对伺服用永磁直线同步电动机进行了比较深入的研究。从提高电机的伺服性能方面：提出了优化气隙磁场的几种方法并对电机气隙磁场进行了优化；提出了采用多相电机消除和抑制电机谐波推力的方法。
