直流与脉流牵引电机结构与制修要求(续) 第六讲 牵引电机的换向与改进换向的措施(续)

Structure of DC and pulsating current traction motors and demands for their manufacture and maintenance

详细列举了牵引电机型式试验、例行试验及研究性试验所需进行的各试验项目,分别介绍了电阻直接消耗法和回馈法两种电机试验线路,并分析其各自的优缺点和试验时应注意的事项。采用回馈法进行了牵引电机的换向试验。

Enumerated are test items of type test,duty test and development test required by DC and pulsating cur rent traction mo tors.This paper introduces two test circuits,such as power consumed on resistance circuit and pow er feed back cir cuit,and gives the notices of each test.Commutation test of traction motor is carried out wtih pow-er feed back cir cuit.
