Abstract

The utility model discloses a high speed permanent magnet synchronous motor stator punching sheet. A body of the stator punching sheet is circular, and the outer contour diameter of the body is 550mm. The inner contour diameter of the body is 190mm. Twhenty seven rectangular stator punching sheet grooves uniformly distributed around a circumference are arranged in the stator punching sheet body. The width of an opening of each punching sheet groove is 15.3mm. The depth of each groove is 111.7mm. Ventilating slots are arranged at positions which are 35mm away from the opening of each stator punching sheet groove. Eight dovetail-shaped positioning grooves uniformly distributed around a circumference are arranged on the outer contour of the stator punching sheet body. The stator punching sheet is reasonable in structure, and is applied to a stator iron core of a high speed permanent magnet synchronous motor YYG400-1120kW18000r/min3000V. The motor stator punching sheet is good in magnetic conductive performance, and can raise the operation efficiency of the motor. The motor stator punching sheet is also with good heat radiation conditions, and the grooves are relatively deep so that coils in the grooves are stable and will not easily loosen or run out of the grooves.
