Abstract

The invention provides a motor and a train. The motor includes a rotating shaft, a rotor assembly, a terminal box, a stator assembly, and a first pressure ring, the rotor assembly is connected to the rotating shaft, the first pressure ring is connected to the stator assembly, and part of the first pressure ring Located inside the junction box, the junction box is arranged on a side of the stator assembly away from the rotating shaft, and the junction box does not coincide with the projection of the stator assembly in the direction of the rotating shaft. In the motor and the train, the junction box and the pressure ring are cast into one body, which reduces the longitudinal design size of the entire motor, and at the same time well avoids the risks caused by welding.

Description

technical field [0001] The invention relates to the technical field of motors, and 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 transition steps in the vehicle. It also has the advantages of low line construction cost, energy saving and environmental protection, flexible grouping, and the safety and comfort of passengers. Convenient to get on and off. However, the too low 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 wheelset, which occupies 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, the traditional arrangement of the driving device on the bogie must be changed, and wh...
