1.前言内燃机车、动车用牵引电动机因安装在转向架上,就必然要求其体积要小重量要轻。由于目前的发展形势要求进一步提高运输能力,因此迫切要求增加牵引电动机的单机功率,而牵引电动机的工作条件很差,如起停频繁、运行中振动大、又有雨水、灰尘的侵入等。牵引电动机从小型重量轻的角度与一般工业用的电机相比,温度上限取得高。为适应这一点,采用耐热性高的绝缘系统。而牵引电动机的绝缘系统要求能适应上述的使用条件,具
1. Foreword Diesel locomotive, motor car traction motor installed on the bogie, it is bound to require the smaller size to light weight. As the current development situation requires further improvement of transport capacity, it is urgently required to increase the stand-alone power of the traction motor. However, the traction motor has poor working conditions, such as frequent start-stop, large vibration in operation, intrusion of rainwater and dust, and the like. Traction motor from a small, lightweight point of view compared with the general industrial motor, the high temperature limit. In order to adapt to this, the use of high heat insulation system. The traction motor insulation system requirements to adapt to the above conditions of use, with
