Abstract

[목적][purpose]

로터케이스의 외주면에 형성한 밸런스웨이트 부설용의 U홈을 스톱퍼 받이로하여 겸용함과 동시에 U홈에 접촉하는 스톱퍼를 축방향으로 짧게하고, 낮은 코스트화 및 축방향의 소형화를 도모한다.By using the U-groove for placing the balance weight formed on the outer circumferential surface of the rotor case as a stopper receiver, the stopper in contact with the U-groove is shortened in the axial direction, and low cost and miniaturization in the axial direction are achieved.

[구성][Configuration]

여러극에 착자된 로터마그넷트(6)가 스테이터코어(8)의 주면과 대향 하도록 배치된 모터에 있어서, 로터마그넷트(6)를 유지한 로터케이스(15)의 외주면에 U홈(15A)을 형성함과 동시에, 이 U홈(15A)내에 밸런스웨이트(22)를 부설하고, 로터케이스(15)가 빠져나가는 방향으로 이동했을때에 U홈(15A)의 일부에 접촉하는 스톱퍼(21)를 설치하여 이루어지는 구성이다.In a motor in which the rotor magnets 6 magnetized in multiple poles are arranged to face the main surface of the stator core 8, the U groove 15A is provided on the outer circumferential surface of the rotor case 15 holding the rotor magnets 6. At the same time, the balance weight 22 is placed in the U groove 15A, and the stopper 21 comes into contact with a part of the U groove 15A when the rotor case 15 is moved in the direction of exit. It is a configuration made by installing.
