摘　　要：大电机机械耗占电机总损耗比例较大,是导致电机效率较低的主要因素之一。电动机转轴和轴承之间,转子、风扇和冷却介质之间的摩擦及风路产生的损耗之和,是电机产生机械损耗的主要途径。由于电机结构中风路结构不合理,所以风在风路损失的能量很多。针对IC611冷却方式电机外风扇风扇罩内风路进行优化设计,从而降低风在风路中的损耗,提高了电机效率。Mechanical loss is one of the main factors which cause low efficiency of the large motor, sum of mechanical loss, friction among stator, fan and cooling media, loss caused by wind path and other losses, are main approaches of mechanical loss of the motor, in that case, optimization design is taken to wind path in fan housing of external fan of the motor cooled by IC611 method, then wind loss in wind path is reduced, motor efficiency is improved.
