Embodiment

[0035] figure 2 Schematic diagram of the structure of the stator punch 200 provided in this embodiment; image 3 A schematic diagram of the structure of the stator punching 200 provided in this embodiment compared with the existing stator punching 200 . Please also refer to Figure 2 and image 3 , in this embodiment, the stator punch 200 includes a stator yoke.

[0036] The stator yoke includes a yoke outer surface 210 and a yoke inner surface 220 .

[0037] The inner surface 220 of the yoke is circular, and the inner surface 220 of the yoke is provided with a plurality of winding grooves 221. The groove depth direction of the winding grooves 221 extends along the direction of the inner surface 220 of the yoke toward the outer surface 210 of the yoke, and is used for winding the set sub-winding.

[0038] The outer surface 210 of the yoke includes a first side 211 and a second side 212 opposite to each other and a first arc 213 and a second arc 214 opposite to each other. ...

Abstract

The invention provides a stator punching sheet and a three-phase motor, and belongs to the technical field of three-phase motors. The stator punching sheet comprises a stator yoke. The stator yoke comprises a yoke outer surface and a yoke inner surface. The yoke inner surface is round, a plurality of wire winding grooves are formed in the yoke inner surface, and groove depth direction of the wirewinding grooves extends towards the yoke outer surface along the yoke inner surface. The yoke outer surface comprises a first side face, a second side face opposite to the first side face, a first arc-shaped face and a second arc-shaped face opposite to the first arc-shaped face, one end of the first arc-shaped face is connected with one end of the second arc-shaped face, the other end of the first arc-shaped face is connected with one end of the first side face, and the other end of the second arc-shaped face is connected with one end of the second side face. According to the stator punchingsheet of the three-phase motor, a structure with a square edge and an arc-shaped edge is used, generated waste can be reduced, and material waste is avoided.

Description

technical field [0001] The invention relates to the technical field of three-phase motors, in particular to a stator punch and a three-phase motor. Background technique [0002] The existing stator stamping sheet 100 of the existing three-phase motor is generally a circular structure or a nearly circular structure, such as figure 1 , the distribution of the magnetic field lines of the motor is reasonable, and the design of the motor can design a motor with ideal performance according to the distribution of the magnetic field lines of the motor. [0003] However, in the process of mass production of the existing stator sheet, a large amount of waste materials will be generated, and the utilization rate of the motor material is low. Contents of the invention [0004] The purpose of the present invention is to provide a stator stamping, which can reduce the generation of waste materials and avoid the waste of materials. [0005] Another object of the present invention is to...
