用定子叠频法进行温升试验时被试电机的气隙磁场、损耗及温升

Air Gap Field,Losses and Temperature Rise of Tested Motor During Temperature Rise Test by Mixed-frequency Method of Stator

简述用定子叠频法进行温升试验的方法及线路,定性地分析用定子叠频法进行温升试验时,被试电机气隙磁场、损耗,并对定子叠频法温升试验值比直接负载法温升试验值稍大的原因做了分析。

The paper presents the methods and circuit of temperature rise test by mixed-frequency method of stator. It also analyses the air gap field and losses of the tested motor during temperature-rise test by mixed-frequency method of stator,and analyses the reason why the tested value is higher than that of direct load method.
