Abstract
The utility model relates to a motor stator punching sheet. The motor stator punching sheet comprises a stator punching sheet body (1), and is characterized in that, the outer contour of the stator punching sheet body (1) is formed by four straight line segments (2) and transition arc segments (3) connecting adjacent straight line segments (2), wherein adjacent straight line segments (2) are perpendicular to each other, and alternative straight line segments (2) are parallel to each other; a central round hole (5) is arranged at the center of the stator punching sheet body (1), and a plurality of primary winding grooves (6) and secondary winding grooves (7) are uniformly arranged on the circumference of the central round hole (5); the primary winding grooves (6) are larger in size than the secondary winding grooves (7); and an annular stator punching sheet yoke part (4) is formed by the outer contour of the stator punching sheet body (1) and the contours of the primary winding grooves (6) and the secondary winding grooves (7). The motor stator punching sheet provided by the utility model improves the utilization rate of materials, saves the production cost and ensures the good performance of the motor.
Description
Technical field
The utility model relates to motor component manufacturing technology field, particularly a kind of motor stator punching.
Background technology
In motor stamping is made, in order to improve stock utilization, often the cylindrical of round punching is cut edge, if but cut edge the rear grooved that does not change motor stator, can cause that the inhomogeneous motor stator yoke section magnetic that causes of magnetic circuit is close too high, affect motor performance, can to save material and do not reduce again motor performance in order to reach, by the improvement design to motor stator punching, and adjust the motor stator winding distribution, can compensate the magnetic circuit loss of the part of cutting edge.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of motor stator punching, has improved the utilance of material, has saved production cost, has guaranteed that the motor runnability is good.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor stator punching is provided, comprise the stator punching body, described stator punching body outline is comprised of with the transition circle segmental arc that is connected the adjacent straight line segment four straightways, described adjacent straightway is mutually vertical, described straightway of being separated by is parallel to each other, the center arrangement of described stator punching body has center hole, be furnished with uniformly several main winding grooves and auxiliary winding groove on the circumference of described center hole, described main winding groove is larger than the size of auxiliary winding groove, described punching body outline and main winding groove, the profile of auxiliary winding groove consists of the stator punching yoke section of ring-type.
Described several main winding grooves are symmetrical about the center of circle of center hole.
Described several auxiliary winding grooves are symmetrical about the center of circle of center hole.
Beneficial effect
The utility model relates to a kind of motor stator punching, has improved the utilance of material, has saved production cost, and the appropriate design copper factor guarantees that the motor runnability is good.
