摘　　要：通过对中小型异步电机通风散热结构的分析及现场实测,认为目前Y2、Y3、YX3、YE3电机在维持能效指标的前提下仍有改进余地,特别是中心高为315~500的几个机座号,因其风路不尽完善,致使定子电流密度选的较低,浪费了铜线。现推荐的结构有效地减少浪费,可为业内人士提供一些参考。Based on analysis and field measurement of the ventilation and heat dissipation structure of small-and medium-sized induction motor, it is thought that current Y2, Y3, YX3 and YE3 ranges of motors have room for improvement on the premise of maintaining indicators of energy efficiency, especially for the motors of frame sizes from 315 to 500. Because their unper- fect ventilation circuits result in low stator current density, so copper wire is wasted. The struc- ture proposed in this paper can provide some reference for industry insiders.
