重点介绍了外置封闭式大型三相绕线型异步电动机集电环、刷架通风结构的设计,冷却系统的结构设计,并指出了设计中的关键点。验证了封闭式大型三相绕线型异步电动机集电环各滑环温度均匀性、集电环理论设计与实际测试结果的吻合性。验证了封闭式集电环碳粉收集装置的实用性及改造电机局部结构的可行性。

The external enclosed large threephase wound asynchronous motor slip ring, brush holder, the design of the ventilation structure were mainly introduces. The structure of the cooling system were design, and the key point in design was pointed out. The enclosed large threephase wound asynchronous motor collector ring each slip ring temperature uniformity, collector ring design and actual test results anastomotic theory were verified. The enclosed collector ring carbon powder collection device was practical and motor the feasibility of local structure.
