A stator core structure

Abstract

The invention, which belongs to the motor field, particularly relates to a stator iron core structure comprising a main iron core body and an iron core plastic package rack coating the main iron core body. The main iron core body contains an iron core inner ring, iron core teeth, and gullets, wherein the iron core teeth and gullets are arranged at the outer side of the iron core inner ring and are arranged alternately. The iron core plastic package rack includes an inner ring part arranged on the iron core inner ring and tooth coating parts coating the iron core teeth; the inner side of the iron core inner ring and the outer ends of the iron core teeth are exposed; the inner ring part includes a top cover ring covering the top of the iron core inner ring, a bottom cover ring covering the bottom of the iron core inner ring, and side cover surfaces covering the outer side surface of the iron core inner ring and corresponding to the positions of the gullets; square winding posts are distributed at the outer side of the top cover ring and a binding post is arranged at the inner side of the top cover ring; and a support enhancement part is arranged at the bottom of the binding post. According to the application, because the high-strength square winding posts are arranged at the plastic package rack and the binding post sleeves the iron core inner ring by a support panel, strengths of all components of the plastic package rack is enhances, thereby improving stability of the motor using the stator iron core and prolonging the service life.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a stator core structure. Background technique [0002] The winding posts on the core molded frame on the existing stator core are used to transition the wires from one iron core tooth to another iron core tooth in an orderly and safe manner. The copper wire has a large restraint force when the wire is drawn, and the diameter and strength of the cylindrical winding post are limited. The pressure that cannot support the copper wire often leads to the breaking of the cylindrical winding post. At the same time, the terminal posts on the iron core plastic frame are connected to one side of the plastic frame, and the bottom is suspended, which is easy to be deformed and broken during use. The connection between the plastic frame and the inner surface of the iron core is not tight enough, and it is easy to disengage. Contents of the invention [0003] The object of the present inve...

[0002] The winding posts on the core molded frame on the existing stator core are used to transition the wires from one iron core tooth to another iron core tooth in an orderly and safe manner. The copper wire has a large restraint force when running the wire, and the diameter and strength of the cylindrical winding post are limited. The pressure that cannot support the copper wire often causes the cylindrical winding post to break
