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.
