Research of Key Parameters Identification of Asynchronous Motor Based on DSP

The paper proposed an improved off-line parameters identification method of asynchronous motor based on DSP processor,and detailedly introduced implementation of the parameters identification method of asynchronous motor under static state.It also made parameters identification experiment for two different asynchronous motors using frequency-conversion vector control system which took TMS320F2812 DSP as core.The experiment result showed that the method is accurate and reliable and has strong operability and portability,which is suitable for application of industrial field.
