Stator core with a strucuture to improve assembly characteristics

摘要

Disclosed stator core for motor is comprising: more than one stator core body; a fixing unit, which is arranged at both ends of the stator core body and fixes the stator core body to be a cylindrical shape; a first insulator, which is integrally formed by mold in order to wrap a part of the stator core body and a side surface of plural teeth simultaneously; and a second insulator, which is arranged to have a form corresponding to the first insulator, and which is integrally formed by mold in order to wrap a part of the stator core body and a side surface of plural teeth simultaneously through the assembly with the first insulator, wherein the first simulator and the second simulator are separated from each other by the section wrapping the teeth during the bending process of the stator core body.

1. A stator core with a structure to improve assembly characteristics, the stator core comprising:
at least one stator core body formed as one body by mold for plural teeth to be formed protrusively at regular intervals in the same direction, wherein the stator core body is formed in a cylindrical shape in which both ends are coupled to each other for a designed section of right and left around the teeth; a fixing unit arranged at both ends of the stator core body for fixing the stator core body in a cylindrical shape; a first insulator integrally formed by a mold in order to wrap a part of the stator core body and a side surface of plural teeth simultaneously; and a second insulator arranged to have a form corresponding to the first insulator, wherein the second insulator is integrally formed by a mold in order to wrap a part of the stator core body and a side surface of plural teeth simultaneously through the assembly with the first insulator, wherein the first insulator and the second insulator are separated from each other by the section wrapping the teeth, wherein the first insulator and the second insulator have a bottleneck nearby a position of a bending section of the stator core body, and wherein the bottleneck is configured to be fractured by fatigue, and wherein the bottleneck has a thickness of 0.5 mm or less.
