摘　　要：IE5为国际电工委员会(IEC)于2016年发布的目前全球最高的电动机能效等级。针对IE5能效等级目标开展了三相异步电动机研制。在设计方面,主要考虑采用优质的冷轧硅钢片,尝试不同风扇结构型式和不等匝绕组型式,并针对小功率电机考虑采用铸铜转子工艺方案,降低了电机损耗。在工艺方面,主要考虑提高加工精度,减小定、转子冲片毛刺等,进一步降低电机的空载损耗。样机测试结果表明,效率、功率因数、起动电流、起动转矩、最大转矩、温升等指标均达到设计要求,实现了IE5能效等级三相异步电动机研制目标。IE5,published by International Electrotechnical Commission(IEC)in 2016,is currently the highest energy efficiency of motor in the world.The development of IE5 energy efficiency three-phase asynchronous motor is carried out.For the motor design,we consider to use high-quality cold rolled silicon steel sheet,try different fan structural styles and windings with unequal turns,and use cast copper rotor in low power motors,so as to lower the motor loss.For the process technology,measures to improve the machining accuracy and reduce burrs during stator and rotor punching are applied,so that the no-load loss of the motor can be further reduced.Prototype test results show that the indices including efficiency,power factor,starting current,starting torque,maximum torque and temperature rise all meet the design requirements.The goal of IE5 energy efficiency is achieved.
