Abstract

(목적)
케이싱부분에 개량을 가한 스텝핑 모우터를 제공한다.
(구성)
회전축(1)에 부착된 로우터(2)의 외측에 고정자 철심(4)을 배설하고, 이 고정자 철심(4)의 전후에 설치된 케이싱(10,11)에 각각 장착된 축받침(8,9)에 의하여 회전축(1)의 전후부를 지지한 스텝핑 모우터에 있어서, 케이싱(10,11)을 프레스 성형한 금속판으로서 형성한다. 그리고, 이 케이싱(10,11)의 고정자 철심(4)에 당접하는 부분에 형성한 육박부(10b,11b)에서 고정자 철심(4)의 외주의 일부를 유지한다. 또한, 교호히 설치된 절입부(10c,11c)와 돌편부(10d,11d)에서 축받침(8,9)을 유지하도록 하였다. 육박부(10b,11b)가 고정자 철심(4)의 일부를 덮어씌우므로 먼지의 침입을 막는다. 절입부(10c,11c)와 돌편부(10d,11d)가 축받침(8,9)의 장착을 쉽게 하고 바른 자세를 유지시킨다.

Description

제1도는 본 발명에 관한 스텝핑 모우터의 단면도, 제2도는 제1도중 상부의 케이싱을 아래쪽에서 본 배면도, 제3도는 제2도를 A-A 부분에서 절단한 것의 단면도.

Claims (1)

  1. 회전축에 부착된 로우터의 외측에 고정자 철심을 배설하고, 당해 고정자 철심의 전후에 설치된 케이싱에 각각 장착된 축받침에 의하여 상기 회전축의 전후부를 지지한 스텝핑 모우터에 있어서, 상기 케이싱을 프레스 성형한 금속판으로서 형성하고, 당해 케이싱의 상기 고정자 철심에 당접하는 부분을 육박하게 형성시켜, 당해 육박부분에서 상기 고정자 철심의 외주의 일부를 유지시킴과 동시에, 상기 축받침을 장착하는 부분을 축받침의 외주를 받는 절입부와 축받침의 외측을 받는 돌편부를 교호히 설치시킨 구조를 가진 것을 특징으로 하는 스텝핑 모우터.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
