Abstract

The invention provides a motor and a train. The motor comprises a rotating shaft, a rotor assembly, a junction box, a stator assembly and a first pressing ring, the rotor assembly is connected with the rotating shaft, the first pressing ring is connected with the stator assembly, and part of the first pressing ring is located in the junction box. The junction box is arranged on one side, far away from the rotating shaft, of the stator assembly, and the projection of the junction box and the projection of the stator assembly in the direction of the rotating shaft do not coincide. According to the motor and the train, the junction box and the pressing ring are cast into a whole, the longitudinal design size of the whole motor is reduced, and meanwhile risks caused by welding are well avoided.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor and a train. Background technique [0002] The 100% low-floor light rail vehicle is one of the most advanced urban transportation systems in the world today. It has the characteristics of low entrance height and no transitional steps in the vehicle, and it has the characteristics of low line construction cost, energy saving and environmental protection, flexible marshalling and meeting the safety and comfort of passengers. It is convenient to get on and off the car and so on. However, the low car body places high demands on the drive system of the bogie. [0003] The driving device of the traditional bogie is placed in the middle of the wheel set, occupying most of the space in the middle of the bogie, and cannot achieve a 100% low-floor requirement. Therefore, in order to achieve the requirement of a 100% low floor, it is necessary to change the traditional arrangement ...
