Abstract

누설자속을 줄여 출력을 향상시킬 수 있도록 한 영구자석형 전동기의 회전자가 개시되는바, 이는 중앙에 축이 형성되고, 방사상으로 돌기가 형성된 내부코어와, 상기 내부코어의 외주면에 부착되는 영구자석과, 상기 영구자석이 이탈되지 않도록 양끝단이 돌기가 형성 외부코어 및 상기 내부코어와 외부코어를 연결하기 위한 연결부재를 구비하여 영구자석의 누설자속을 저감시켜 전동기의 출력을 향상시킬 수 있도록 한 영구자석형 전동기의 회전자에 관한 것이다.
또한, 영구자석의 형상을 사다리꼴로 형성하여 영구자석의 극호을 크게 함으로써, 동일체적의 전동기에비해 출력을 향상시킬수 있도록 한 영구자석형 전동기의 회전자에 관한 것이다.
