Abstract:This paper analyzes some existing methods and their problems of measuring flux characteristics of SRM, and presents a indirect method of measuring flux characteristics based on DSP. By measuring current and voltage on the phase winding circuit and transfer them to PC by communication program, combined with a numeric integration, the magnetization characteristics are obtained. The experimental instruments needed in this method are common, and the test platform is easy to be built, thus the expense is lowered in measurement 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.
Keywords:Switched reluctance motor   Flux characteristics    Measurement    Numeric integration
