In this paper, cable drive mechanism is proposed to implement high reduction gear ratio. Cable drive mechanism has great advantages such as light weight, high degree of freedom about design aspect and zero backlashes. However, it is restrictively utilized for robotic applications because it is difficult to implement high reduction gear ratio more than 10 to 1. Proposed mechanism enables multi-level reductions by adopting seamless winding method (SWM) which links the previous output axis and the next input axis. Consequently, this reduces the mechanical complexity significantly and enables high reduction with only one single wire cable. 3D CAD design was provided and prototype was manufactured.
본 논문은 부하상태에 따른 매입형 영구자석 전동기에서의 역기전력 파형을 제시하였다. 유한요소해석에 기초한 고정투자율법을 사용하여 무부하 상태뿐만 아니라 부하상태에 따른 역기전력 파형을 해석하였고, 매입형 영구자석 전동기의 설계변수가 역기전력 파형의 고조파 성분에 미치는 영향을 조사하였다.
