变轨距列车用电动机的开发

Development of Traction Motors for a Gauge Change Train

我们为变轨距列车研制了2种牵引电动机。一种是直接驱动的永磁同步电动机,另一种是传统的万向轴驱动的异步电动机。对这2种电动机进行了试验,取得了良好的结果。在美国对变轨距列车的高速耐久性运行试验进行了约2年。在运行试验中,电动机没有发生任何故障。运行试验后进行的解体检查也表明电动机没有任何损伤。

We have developed two types of traction motors for a gauge change train. One type is a direct drive type synchronous motor usinga rare earth magnet permanent magnet. The other type is a conventional cardan drive asynchronous motor. Type tests of two types of motorsshowed good results. A high speed endurance running test of a gauge change train was carried out in the U.S.A. for about two years. During therunning test, no trouble occurred with these motors. An overhaul inspection after the running showed no damage on the motors.
