A Measurement Method and Equipment of Magnetic Characteristics of SRM

This paper analyzes some existing methods and their problems of measuring flux characteristics of SRM., and presents a DSP based indirect method of measuring flux characteristics. The flux characteristics are obtained from current and voltage measurements on the phase winding circuit, combined with a numeric integration. The experimental instru-ments needed in this method are common, and the test platform is easy to be built, thus the expense is lowered in measu-rement of flux. The test indicates the measuring process is simple to implement, and the experimental results are accurate, which testify the method is suitable to measure the flux characteristics of SRM.
