奇数相方波励磁电机相数选择与转矩的关系

Realation Ship Between the torque and phase chosen of blushless motor in odd phases excited by square wave

从转矩和转矩脉动两方面比较在不同奇数相下方波励磁无刷电机的性能,探讨激磁极极弧度和电机转矩和转矩脉动的关系,得出在不同奇数相下方波励磁无刷电机的电磁转矩脉动最小的条件,从电机绕组电流利用率方面探讨相数选择的数据。

This paper analyses the performance of blushless motor in conditions of different odd phases,mainly focus on the torqe and torque ripple ,also research on the relationship of the angle of the poles and the torque etc.. At last we have the condition of minimum torque ripple and how to choose the phases number of the motor.
