摘要
为提升电动汽车永磁同步电机再制造性能,采用低铁损非晶定子铁心替换了旧电机硅钢定子铁心。基于2D有限元模型,分析了额定转速下,同尺寸非晶定子铁心替换对再制造电机空载、负载性能的影响。替换后,再制造电机的效率提升1.8%,额定负载转矩减小6%。对再制造电机中非晶合金定子铁心槽型尺寸及绕组结构进行了优化。与旧电机相比,优化后的再制造电机效率提高1.9%,额定转矩不变,试验验证了仿真结果的正确性。
In order to improve performance of the remanufacturing electric vehicles with permanent magnet synchronous motor,the waste motor silicon stator was replaced by the low iron loss amorphous stator.Based on 2DFEM analysis,performance of the same dimensional amorphous alloy and silicon stator motor,with load and without load,was compared in rated speed.The results show that the amorphous motor efficiency is 1.8% higher than waste motor,but 6%rated load torque is reduced.To recovery the rated load torque,the design of amorphous stator slot and winding was optimized.The results show that the optimized amorphous alloy stator remanufacturing motor rated load torque is recovery,meanwhile the motor efficiency is improved by 1.9%compared with waste motor.The FEM analysis results was validated by remanufacturing motor experiments.
