Abstract :
The precise determination of permanent magnet synchronous motors (PMSM) parameters is of great significance. By means of PMSM d, q -axis mathematical model and direct current attenuation experiment, a parameter identification technique based method to determine PMSM parameters precisely, is presented in this paper, whose effectiveness is demonstrated by the determined parameters of a 7.5 kW NdFeB PMSM, which are valid and rigorous.
