摘要
在假设ＳＲ电机磁路是线性的条件下，分析了绕组电感和绕组电流随转子位置角的变化规律以及磁链与电流的基本关系；由磁场能量推导出ＳＲ电机的自然机械特性方程式。根据机械特性方程式提出ＳＲ电机两种基本调速方法，即调节相绕组的通电角和调节相绕组的平均电压。
The rules of winding inductance and current changing with the position angle of rotor and the basic relation between flux linkage and current are investigated, assuming that the magnetic circuit of SR motor is linear. And the equation of natural mechanical properties of SR motor is deducted from magnetic field energy. And two basic methods for regulating motor speed are proposed based on this equation. That is to adjust the energizing angle and the average voltage of phase winding.
