G-series high-speed train door driving motor

Abstract

A G-series high-speed train door driving motor belongs to the electric drive technology field, and is composed of a bearing, armature windings, permanent magnets, a pulley, stator iron cores, door plates, a shaft and a guide rail. The pulley fixed on the shaft is located between the two door plates of a G-series high-speed train door, eight fan-shaped through holes are distributed on the circumference of the pulley evenly, and the connection position between two through holes is made of a magnetic conductive material. Nine pairs of sub-stator iron cores are respectively fixed on the two surfaces at the inner sides of the door plates and towards the pulley, the difference of the adjacent two pairs of sub-stator iron cores along a circumferential direction is 30 degrees, one permanent magnet is clamped at the connection position of each pair of sub-stator iron cores, and one concentrated armature winding is wound at the root of an armature pole of each sub-stator iron core. According to the technical scheme of the present invention, the integral design of the G-series high-speed train door driving motor and the pulley is realized effectively, and the G-series high-speed train door driving motor can give full play to the advantage that a disc type motor is large in power density and has a higher application value on a G-series high-speed train sliding door.

Description

technical field [0001] The invention relates to a high-speed rail door driving motor, which belongs to the technical field of electric transmission. Background technique [0002] Traditional railways and rail vehicles often use pneumatic doors, but the pneumatic doors are not flexible enough, the noise is loud during intake and exhaust, the position control accuracy is low, and it is not easy to maintain. After many years of use, it will occur frequently due to pneumatic components and a single door relay. failure. Since the pneumatic door is not suitable for high-speed operation, an electronically controlled electric door that is electrically driven to control the opening and closing of the door is derived. [0003] The electric car door has strong anti-interference ability, can adapt to the operation of the train in the environment of high vibration, high noise and strong interference, and realize the precise control of the door opening and closing. The motor provides po...
