摘要
开关磁阻电动机(SRM)的电流-磁链曲线是分析其内在参数的重要曲线。工程上常采用解析法来计算SRM的电流-磁链曲线。对解析法的一些公式进行了改进。并通过与有限元分析仿真结果进行比较,证实改进后的解析法提高了求解精度,可作为分析SRM电磁参数的理论依据。
Current-flux linkage curves in the switched reluctance motors （SRM） were important for analyzing inherence parameters of SRM and the analytic arithmetic was adopted frequently for calculation of the curves in engineering. The analytic arithmetic was analyzed in the paper and some formulas were ameliorated. Comparison with the result of the finite-element software simulation demonstrates that ameliorated analytic arithmetic can improve operational precision and provide theoretic gist of analyzing electromagnetic parameters in the SRM.
