一种新型矿用电机—复合转子异步电机中谐波转矩及附加损耗的分析计算

Analysis and Computation on Harmonic Torque and Stray Loss for a Composite -Rotor Induction Motor Used in Coal Mine

在上篇谐波磁场三维分析的基础上,对复合转子异步电机中的谐波转矩和附加损耗进行了较详细的分析,提出了实用的计算公式.通过对样机的计算与实测,验证了本文计算方法的准确性,最后提出了降低附加损耗,提高电机性能的各种方法.

On the basis of 3D analysis of the harmonic field for the composite -rotor induction motor,this paper discusses the harmonic torque and stray loss, and proposes simple expressions for their calculation. The results of machine performance calculated by the proposed method are found to be agreed,well with those measured on a prototype machine. This paper also proposes a lot of methods to decrease the stray loss and improve the performance of the motor.
