摘　　要：表面磁钢式低速永磁电动机的铁耗主要为定子铁损，与磁滞损耗相比，涡流损耗计算较为困难，本文基于平均涡流损耗正比于平均磁密变化率平方这一概念，对一台极弧宽度为π的表面磁钢式低速电动机铁耗进行计算，计算结果与实验值较好吻合。The main core losses of surface -mounted low speed permanent - magnet motors is core losses in the stator steel. Compared with the hysteresis losses, the calculation of the eddy current losses is more difficult.Based on the concept that the eddy current losses are propotional to the square of the time rate of change of flux density,this paper calculates the core loss of a surface mounted low speed permanent - magnet motor with π magnet ploe arc,and the calculation result is in good agree ment with the test data.
