As shown in fig. 1, the stator core has a lamination bar structure. The stator punching sheet for the motor is also stamped by a silicon steel sheet. A winding slot 9 is formed between two adjacent teeth of the stator punching sheet, and a coil is wound on the teeth. And a hollow inner round hole is formed in the middle of the stator punching sheet, and after a plurality of stator punching sheets are laminated to form a stator core, the inner round hole of the stator punching sheet forms a rotor hole, and the rotor is arranged in the rotor hole.

When the stator core is manufactured, a piece of annular stator pressing rings are respectively arranged at two ends of the stator core, and the diameter of each stator pressing ring is equal to that of each stator punching sheet. Then, a plurality of strip-shaped press strips are inserted into the press strip grooves, and the two ends of the press strips are bent, so that the two ends of the press strips extending out of the stator press ring are respectively pressed on the stator press ring. And finally, welding two ends of the pressing strip on the stator pressing ring to fix the pressing strip and the stator pressing ring.
However, the manufacturing process of the stator core is complex, and the lamination, the bead loading and the welding of the stator punching sheet are generally realized by using a special lamination riveting device.
