用铁基非晶合金转子铁心替换原电机中的硅钢转子铁心,基于有限元软件Ansoft分析了非晶转子铁心替换对电机性能的影响。与原电机相比,再制造电机的转矩提升了2.6%,效率提高了0.05%,齿槽转矩幅值大幅增加。采用定子斜槽削弱其齿槽转矩,当斜槽精确为一个齿距时,电机的齿槽转矩幅值为0.128 N·m,相比于未采用斜槽时的再制造电机减小了92.36%,相比于原电机减小了38.46%。

Replacing the silicon steel rotor core of original motor by the amorphous alloy rotor core, effects of amorphous alloy rotor core on the performance of motor was analyzed based on finite element software Ansoft. Compared with the original motor, the load torque of the remanufacturing motor was enhanced by 2.6%, the efficiency was 0.05% higher, and the cogging torque was highly improved. In order to reduce the cogging torque, stator with skewed slots was adopted. When the skewed slot number was 1, the cogging torque of the motor was 0.128 N·m, which was reduced by 92.36% compared with the remanufacturing motor and was 38.46% lower than the original motor.
