상기 하우징(2)의 내부에는 그 단면이 'ㄷ'자 모양으로 절곡 형성되어 일측 끝단이 구동축(1)과 연결되어 있는 회전자 결합부(6)를 형성하고, 상기 회전자 결합부(6)의 내주면상에 영구자석으로 이루어진 회전자(5)를 형성함으로써, 회전자(5)의 회전력이 구동축(1)으로 전달될 수 있도록 한다.The inside of the housing (2) is bent in a cross-section '' 'shape to form a rotor coupling portion 6, one end of which is connected to the drive shaft (1), the rotor coupling portion (6) By forming the rotor (5) consisting of a permanent magnet on the inner peripheral surface of the, the rotational force of the rotor (5) can be transmitted to the drive shaft (1).

한편, 상기 회전자(5)에 대응하는 고정자(7)의 형성을 위하여, 상기 하우징(2)의 측면부를 이루는 엔드벨(3)과 엔드벨캡(4)의 사이에 고정자 지지대(8)를 형성하고, 상기 고정자 지지대(8)의 외주면상에 고정자(7)를 형성한다.Meanwhile, in order to form the stator 7 corresponding to the rotor 5, a stator support 8 is formed between the end bell 3 and the end bell cap 4 forming the side portion of the housing 2. The stator 7 is formed on the outer circumferential surface of the stator support 8.

또한, 상기 고정자 조립체가 회전할 수 있도록 하는 회전장치를 형성하는데, 상기 회전장치는 상기 고정자 지지대(8)의 외주면상에 형성되는 회전기어(10), 그리고 엔드벨 캡(4)의 외주면상에 형성되어 상기 회전기어(10)에 의한 고정자 조립체의 회전시 고정자(7)의 회전을 안내하는 복수 개의 슬라이드 바(11)를 포함한 것이다.In addition, the stator assembly forms a rotating device for rotating the rotating device, which is formed on the outer peripheral surface of the stator support 8 and the outer peripheral surface of the end bell cap 4.
