摘　　要：选dq坐标下的电机模型,用3阶EKF算法,来估计电机定子绕组的电阻值和转子磁体的磁通量,和静态时20℃室温下测得的定子绕组阻值和转子磁通量作比较,进而计算出对应的电机定子绕组和转子绕组的温度值.电阻值估计和磁通估计分别独立进行,通过对实验电机的实际测量和估计值进行比较具有较好的一致性.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.
