Abstract

The invention discloses a stator punching sheet structure and a motor comprising the same. The stator punching sheet structure comprises a plurality of stator iron core groups; one stator iron core group is provided with 9-12 stator iron core pieces; a stator bending groove is arranged between every two adjacent stator iron core pieces; each stator bending groove comprises a curved surface A, a curved surface B and a curved surface C, wherein the curved surface A and the curved surface B are each provided with multiple arcs with the same number, and the curved surface C is in an arc shape; after each stator iron core group is bent, the multiple arcs on the curved surface A can coincide with the multiple arcs on the curved surface B; and the multiple stator iron core groups are connected end to end to form stator iron core layers. The motor comprising the stator punching sheet structure comprises a rotor body; and the stator core layers are stacked in sequence to form a stator body; the stator body is wound and then put into a mold so as to be subjected to injection molding; and the rotor body is also put into the mold so as to be subjected to injection molding.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator punching structure and a motor including the punching structure. Background technique [0002] The motor punching sheet, also known as the stator core, is one of the important components of the motor. Its main function is to generate a magnetic field and mechanically support the motor. The motor consists of three parts: stator core, stator winding and frame. The stator winding is embedded in the stator core, and the induced electromotive force is generated by the current to realize the conversion of electric energy. [0003] The traditional stator core is combined by fan-shaped pieces, and its material utilization rate is relatively low, basically only about 36%. During the stator processing, the low material utilization rate will increase the manufacturing cost. After the stator core is stamped on the mold, it is formed by bending. When the existing stator core is bent...
