| titleOfInvention | Stator punching piece, stator core and motor |
| abstract | The present disclosure discloses a stator punching piece, stator core and motor. The stator punching piece is formed by die stamping. An outer circumference of the stator punching piece is provided with a continuous concave-convex structure extending in an axial direction of the stator punching piece for a cooling medium to flow therethrough, so as to increase an heat dissipation area of an outer circumference of a stator core composed of the stator punching pieces and improve a flow state of the cooling medium on the outer circumferential surface of the stator core, thereby increasing a rated power and rated torque of a motor. Since the stator punching piece is formed by die stamping, changing the shape of the outer edge of the stator punching piece has no effect on the manufacturing cost of the motor. Without increasing the cost, the rated power and rated torque of the motor can be increased by 5-10%. |
