双流制窄轨电力机车用异步牵引电机设计

将牵引电机应用于双流制窄轨电力机车时,由于窄轨机车轨距小,所以牵引电机安装空间异常狭小,比一般牵引电机在安装空间、电机结构、电磁负荷等方面的要求更加苛刻。针对窄轨双流制电力机车的运用特点和特殊要求进行了分析,提出了牵引电机的设计要求和关键技术难点,并对关键技术难点给出了相应的分析和解决措施。对该牵引电机的制造过程及电机试验测试情况进行了论述。试验结果表明,该牵引电机达到了设计预期,完全能满足设计要求。

Design of Asynchronous Traction Motor for DualVoltageNarrow Gauge Electric Locomotive

Asynchronous traction motor was developed for dualvoltage electric locomotive on narrow gauge track. The gauge of the narrow gauge locomotive was smaller than the standard gauge, which resulted in the abnormally small installation space of the traction motor. The requirements for installation space, motor structure and electromagnetic load were more difficult compared to those of other traction motors. The application characteristics and special requirements of dualvoltage narrow gauge electric locomotive were analyzed. The design requirements and key technical difficulties of traction motor were put forward. The manufacturing process and the testing process of the dualvoltage traction motor were described. The test results show that the traction motor successfully meets all design requirements.
