符合新2级效率等级的三相异步电动机研制

摘要

国标GB 18613－2012《中小型三相异步电动机能效限定值及能效等级》自2012年9月1日起已正式开始实施，现就研制符合该标准新2级效率等级的（即达到IE3超高效率等级）三相异步电动机进行介绍。%The national standard GB 18613-2012“Minimum allowable values of energy efficiency and energy efficiency grades for small and medium three-phase asyn-chronous motors”has been officially put into effect since September 1, 2012. The research and manufacture of this type of three-phase asynchronous motor in accordance with new grade 2 efficiency rating ( i.e. IE3 premium efficiency rating)were introduced.
