Abstract
The utility model discloses a kind of stator punching sheet, stator core, stator assembly and motor, the stator punching sheet includes: yoke part, yoke part is annular;Multiple tooth parts, tooth part is connected with yoke part and extend along the radial direction of yoke part inward, multiple tooth parts are arranged along the circumferential direction of yoke part, and the cooperation between two adjacent tooth parts defines stator slot, the number of stator slot is multiple, multiple stator slot includes first slot and second slot, in the plane where the stator punching sheet is, the area in first slot is less than the area in second slot, wherein, the stator punching sheet satisfies:1.85≤d2 / d1≤2.05,0.95≤d3 / d2≤1.05, d1 is the width of tooth part, d2 is the minimum distance between first slot and the outer circumferential edge of yoke part, d3 is the minimum distance between second slot and the outer circumferential edge of yoke part.According to the stator punching sheet of the utility model, the magnetic density saturation degree of tooth part and yoke part can be more uniform, and the motor output torque performance is significantly improved.
