Abstract

본 발명은 서보 전동기의 회전력을 발생시키는 자속의 누설을 억제하면서 금형 제작이 용이하고, 기하학적으로 안정적이며, 코깅 토오크가 작은 최적화된 형상의 서버 전동기의 고정자 철심을 제공할 수 있도록 한 것이다.The present invention is to provide a stator iron core of an optimized shape server motor with easy mold fabrication, geometrical stability, and low cogging torque, while suppressing leakage of magnetic flux that generates rotational force of the servo motor.

이를 위해, 본 발명은 고정자 철심(1)의 치형부(2)와 치형부(2) 사이를 연결하는 교각부(3)의 형상이 원호형상을 이루게 되는 서보 전동기의 고정자 철심이다.To this end, the present invention is a stator iron core of a servomotor in which the shape of the piercing portion 3 connecting the teeth 2 and the teeth 2 of the stator iron core 1 forms an arc shape.
