Abstract

본 발명은 전동기의 고정자철심에 관한 것으로서, 본 발명의 목적은 고정자철심 내측에 형성된 다수의 슬롯 내에 삽입된 동선을 보호 및 지지하는 지지부재를 변형시켜 동선 지지공정의 간략화와 부품감소에 따른 제품의 생산성 향상 및 원가절감과 동선이 견고히 지지되는 전동기의 고정자철심을 제공하는데 있다.The present invention relates to a stator core of an electric motor, and an object of the present invention is to deform a support member for protecting and supporting a copper wire inserted into a plurality of slots formed inside the stator core, thereby simplifying the copper wire supporting process and reducing the parts. To improve productivity, reduce cost, and provide stator cores of electric motors with solid copper wire.

이와 같은 목적을 실현하기 위한 본 발명에 따른 전동기의 고정자철심은 중앙에 회전자축부가 삽입되도록 축공이 형성되고 일측이 개방되어 축공과 연통되며, 동선이 삽입되는 다수의 슬롯이 형성된 제2고정자철심과, 상기 제2고정자철심의 슬롯과 대향위치에 동일수와 형상의 슬롯 및 제2고정자철심 축중의 내경보다 큰 내경을 갖는 축공이 형성되어 제2고정자철심의 양측에 부착되는 제1고정자철심과, 상기 제1고정자철심의 축공 내측면에 삽입되는 링형상의 지지부재가 포함되는 것을 본 고안의 요지로 한다.The stator core of the motor according to the present invention for achieving the above object is the shaft hole is formed so that the rotor shaft portion is inserted in the center and one side is open and in communication with the shaft hole, the second stator iron core with a plurality of slots are inserted into the copper wire is inserted; The first stator core is attached to both sides of the second stator core, the shaft hole is formed in the opposite position to the slot of the second stator core core and the shaft hole having an inner diameter larger than the inner diameter of the second stator core core shaft; The gist of the present invention includes a ring-shaped support member inserted into the inner surface of the shaft hole of the first stator core.
