Abstract

The invention relates to a winding stator structure and a motor. The winding stator structure comprises a stator yoke part and a plurality of stator tooth parts, wherein the stator yoke part is provided with a plurality of first insertion grooves; the stator yoke part is divided to a plurality of yoke part blocks along the circumferential direction; the plurality of yoke part blocks are sequentially connected to form the stator yoke part in a surrounding mode; the plurality of stator tooth parts and the first insertion grooves are arranged correspondingly; each stator tooth part comprises a first plug part, and the first plug part is inserted to the first insertion groove. As a stator tooth part with a quality problem is not connected with the stator yoke part or other stator tooth parts, the stator yoke part and other stator tooth parts are not influenced; similarly, as a yoke part block with a problem is made independently, other stator tooth parts and other yoke part blocks are not influenced. Thus, according to the above winding stator structure, the phenomenon of a high reject rate in the case of overall blanking of the stator yoke part can be avoided, the sheet utilization ratio can be improved, and the stator iron core material cost is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a winding stator structure and a motor. Background technique [0002] The winding stator structure is mainly composed of coils and stator cores. In order to obtain better motor performance, the slot width design of the stator core is usually much smaller than the slot width. However, this imposes high requirements on the machining accuracy of the stator core, increases the reject rate, and increases the production cost. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art, and provide a winding stator structure and a motor, which can reduce the scrap rate and production cost. [0004] The technical solution is as follows: a winding stator structure, including: a stator yoke, the stator yoke is provided with several first slots, the stator yoke is divided into several yoke parts along its circumference, and several The yoke...
