Abstract:
dq coordinates motor model is selected，with 3-order EKF algorithm to estimate the stator winding resistance and rotor winding magnet flux． Then compared with the stator resistance and rotor flux which measured under 20℃ room temperature when in static，and the corresponding stator winding and rotor winding temperature are calculated． Resistance and flux estimates were estimated independently． On the experimental motor，actual measurements and estimated values are compared with good agreement．
