For example, the core part 116 may include a first core assembly 116a having a rotation shaft 310 coupled to a center thereof, and a first core assembly 116a having a space in which the second excitation stator 130 is inserted therebetween. The second core assembly 116b disposed on the outside of the second core, and the third shaft assembly 116c to which the rotary shaft 310 is coupled to the center and the first and second core assemblies 116a and 116b are coupled through the fastening member. It can be composed of).
특히, 제 2 코어 어셈블리(116b)의 외경측에는 제 1 여자 고정자(120)에 대향되게 배치되고 자석부(112)가 삽입되므로, 제 1 여자 고정자(120)와의 자기 유도를 통해 제 1 여자 고정자(120)에서 유도 전기가 생성될 수 있도록 할 수 있다. 그리고 제 2 코어 어셈블리(116b)의 내경측은 제 2 여자 고정자(130)에 대향되게 배치되어 코일부(113)가 권선되므로, 제 2 여자 고정자(130)와의 전자기 유도를 통해 여자 전기를 생성할 수 있다, 또한, 제 2 코어 어셈블리(116b)에는 자석부(112)와 코일부(113) 사이에 이들 간의 자력선의 간섭을 방지하기 위한 비자성부(114)가 마련될 수 있다. 이 비자성부(114)는 중공의 원통형 형태로 제공될 수 있다.In particular, the outer side of the second core assembly 116b is disposed opposite to the first excitation stator 120 and the magnet 112 is inserted, so that the first excitation stator ( Induction electricity may be generated at 120. In addition, since the inner diameter side of the second core assembly 116b is disposed to face the second excitation stator 130 so that the coil part 113 is wound, excitation electricity may be generated through electromagnetic induction with the second excitation stator 130. In addition, the second core assembly 116b may be provided with a nonmagnetic portion 114 to prevent interference between magnetic lines of force between the magnet portion 112 and the coil portion 113. This nonmagnetic portion 114 may be provided in a hollow cylindrical shape.
상술한 바와 같이, 본 발명은 여자 회전자의 여자 전기를 주 발전 장치의 주 회전자에 유선으로 직접 제공할 수 있으므로, 별도의 슬립링이 불필요하고, 적외선 통신의 미사용으로 품질향상과 제품 원가를 줄일 수 있는 등의 우수한 장점을 갖는다.As described above, the present invention can provide the excitation electricity of the excitation rotor directly to the main rotor of the main power generation device by wire, so that no separate slip ring is required, and the improvement of product quality and product cost due to the non-use of infrared communication. It has excellent advantages such as being able to reduce.
