Problems solved by technology

[0003] Due to the wide yoke stator core, it is currently impossible to use conventional winding methods to achieve
Therefore, the stator core with a wide yoke is basically formed by stamping out a single silicon steel sheet and then laminated or made of a high magnetic permeability core material at one time, which has high production costs and low work efficiency.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as Figure 11-12 As shown, the stator core is divided into a trough-shaped part body 1 and a yoke part body 2. The above two parts are respectively wound into a helical circle by a winding method and then arranged and formed. The formed yoke part body 2 is sleeved in the groove The outer ring of the shaped part body 1 is integrated to form a whole iron core.

[0026] Such as Figure 2-4 As shown, the trough part body 1 of the present invention is axially wound into a circular and spiral loose semi-finished product with a predetermined number of turns, and then through the first finishing, welding, rivets or self-fastening are used to sort it into an integrated form.

[0027] Such as Figure 5-7 As shown, the body 2 of the yoke portion of the present invention is axially wound into a circular and spiral loose semi-finished product with a predetermined num...

Abstract

The invention discloses an improved structure of a stator iron core. The stator iron core comprises a groove-shaped part body and a yoke part body, wherein the two part bodies are wound into spiral circles in a winding manner and subjected to finishing forming, and the yoke part body subjected to the finishing forming is arranged on an outer circle of the groove-shaped part body in a sleeving manner to be integrated with the groove-shaped part body so as to form an iron core integral body. According to the improved structure provided by the invention, the stator iron core with a wide yoke part incapable of being produced in the winding manner originally comprises the groove-shaped part body and the yoke part body which can be separately formed in the winding manner, and the two parts are integrally formed by winding and integrated by utilizing a thermal sleeving process; and the stator iron core after the integration ensures relatively high air-gap magnetic flux density, easily realizes high torque density and serves as a transmission application of large torque driving.

Description

technical field [0001] The invention relates to the structure of a stator iron core, in particular to an electronic iron core suitable for various motors. Background technique [0002] At present, in the production method of winding stator core, there is a process of winding the stamped and formed strips into spiral stator laminations. In this process, only space constraints are used for the strips. During the winding process, The return spring exerts a unilateral axial force on the drive disc, forcing the drive disc to bear unilaterally in the axial direction, and when it rotates, it produces eccentric load swings, and the coiled deformation space between the limit plate and the end face of the drive disc occurs periodically. Irregular changes in the belt, resulting in harmful deformation defects in the yoke of the punching belt - wrinkles (such as figure 1 As shown), the rule is: the larger the yoke width of the motor stator core, the more serious the wrinkles; the larger...
