摘要
开关磁阻电动机（ＳＲＭ）的双凸极结构使其电磁特性呈高饱和性和高度非线性．对ＳＲＭ进行分析、设计与驱动控制，必须深入研究ＳＲＭ的磁化特性曲线ψ（θ，ｉ）．本文在对ＳＲＭ电磁特性及磁化特性曲线的特点深入分析的基础上，提出了一种新的ＳＲＭ磁化曲线模型，该模型既有令人满意的工程精度，又具有计算速度快的特点．
The Double-Sailent structure of Switched Reluetance Motor(SRM) makes the electromagnetic characteristics of the motor to be saturable and nonlinaer in high degree.It is necessary to deeply investigate the character of magnetising curves ψ(θ,i),for analysis,design and control purposes.Based on analysing on the feature of electromagmetic characteristics and magnetising curves,The paper provides a new modelling method for the magnetising carves of SRM,which has satisfying engineering accaracy and fast calculating speed.
