摘要：针对现有开关磁阻电机磁链特性的几种测量方法及其存在的问题，提出一种半周期激励的在线测量磁链特性方法，该方法无需了解电机具体参数，通过构建基于DSP的在线检测系统，在测量前对磁链等效电阻核准和优化，最后在上位机中采用离散方法计算磁链值，从而获得不同角位置和电流时的电机磁化曲线族。最终通过实验验证了理论的正确性与实用性。

Abstract: This paper analyzed some existing methods and the problems of measuring flux characteristics of SRM, and put forward the method of online measuring flux characteristics of a semi periodic excitation.Without understanding the specific parameters of the motor under the condition of data, and presented a DSP based online detection system of flux linkage characteristic, approved and optimized the flux equivalent resistance before measurements.Using the discrete method to calculate the flux value in the host computer,to obtain the motor magnetization curves of different angular position and current.Finally,the experimental results verified the correctness and practicability of the theory.
Key words: switched reluctance motor; flux characteristics; equivalent resistance;halfcycle
