More Information
Summary:A magnetic geared line-start permanent magnet synchronous motor using a magnetic gearing effect, according to the present invention, comprises: a fixed-type rotor which does not rotate in a fixed state and supplies a magnetomotive force by a permanent magnet; a polepiece rotor which is formed by connecting a polepiece core and a non-magnetic filling material alternatingly towards an outer side of the fixed-type rotor; a stator core which is formed towards an outer side of the polepiece rotor and has power injected to wound coils applied thereto; a conductor cage which is coupled with the polepiece rotor to generate a start torque; and an external box which is fixed to an external fixed structure to fix the fixed-type rotor inside. The motor has a very high degree of freedom of a design and does not require a location sensor, thereby having a very simple structure. 본 발명에 따른 자기 기어 효과를 이용한 마그네틱 기어드 직입기동형 영구자석 전동기는 고정된 상태로 회전하지 않고, 영구자석에 의한 기자력을 공급하는 고정형 회전자; 상기 고정형 회전자의 외측으로 폴피스 코어와 비자성 충전재가 번갈아가며 연결되어 형성된 폴피스 회전자; 상기 폴피스 회전자의 외측으로 형성되어 권선된 코일로 투입되는 전원을 인가받는 고정자 코어; 상기 폴피스 회전자와 결합하여 기동 토크를 발생시키는 도체 케이지; 및 외부의 고정 구조물과 고정되어 내부의 상기 고정형 회전자를 고정시키는 외함;을 포함하여 설계의 자유도가 매우 높은 효과가 있고, 위치센서의 필요성이 없음으로 그 구조가 매우 단순한 효과가 있다.
