定转子材料组合方式对再制造电机性能影响

为节约资源和提升原电机性能,将非晶材料与硅钢材料组合应用于定转子铁心进行电机再制造。根据定转子材料不同组合方式提出3种再制造方案,基于Ansoft Maxwell分析了不同组合方式对再制造电机磁密、转矩及脉动、铁耗、效率和齿槽转矩等性能的影响,确定了最佳再制造方案,并基于近似叠加算法,采用分段设置定子斜槽削弱了齿槽转矩。与原电机相比,再制造电机铁耗降低51.73%,转矩提高1.43%,转矩脉动降低6.45%,效率提升0.75%,齿槽转矩优化后降低为原电机的19%,表明了再制造电机的优越性

Effects of Material Combinations of Stator and Rotor on the Performance of Remanufactured Motors

In order to save resources and improve the performance of the original motor,the combination of amorphous material and silicon steel material is applied to the stator and rotor core for motor remanufacturing. According to different combination methods of the materials of stator and rotor, three remanufacturing schemes were proposed.Based on Ansoft Maxwell, the effects of different combination modes on the magnetic density, torque and pulsation, iron consumption, efficiency and cogging torque of the remanufacturing motor were analyzed, and the optimal remanufacturing scheme was determined. Based on the approximate superposition algorithm, the cogging torque was weakened by piecewise setting of the stator slot.Compared with the original motor, the iron consumption of the remanufactured motor is reduced by 51.73%, the torque is increased by 1.43%, the torque pulsation is decreased by 6.45%, the efficiency is increased by 0.75%,and the cogging torque is reduced to 19% of that of the original motor, indicating the superiority of the remanufactured motor
