| 摘 要： | 通过引入互感的方法,表征开关磁阻电机相邻两相同时励磁条件下的每相磁链与单相励磁条件下每相磁链的差别,建立了互感的计算模型,采用实验的方法测取了样机的自感特性和互感特性,分析了互感随转子位置和相电流的变化规律。理论分析了两相励磁条件下互感对输出转矩的影响,并通过实验进行了验证。推导了计入互感时的相电压平衡方程和转矩建模方法,在此基础上完成了调速系统的建模和仿真。研究表明:偶数相开关磁阻电机存在电磁不对称励磁相,长磁路励磁相的负互感使输出转矩有所减小,一个导电周期内转矩波形不规则,转矩脉动有所增加,本文可为开关磁阻电机的准确建模及高性能控制提供理论依据。

| Abstract: | The difference of phase flux linkage in two-phase excitation mode and in single-phase excitation mode is characterized by mutual inductance for switched reluctance motor. The calculation model for mutual inductance is developed. The self and mutual inductance characteristics are detected by experiment, and the variation of mutual inductance with respect to rotor position and phase current is analyzed. The effect of mutual inductance on torque output is theoretically analyzed and validated by experiment. The... |
