초고속 자기부상열차 추진시스템용 선형 동기 전동기의 추력 리플 저감을 위한 근사최적 설계

In this paper, the basic design of linear synchronous motor(LSM) for high speed propulsion system is performed. By characteristics analysis of designed LSM, peak to peak magnitude of thrust force ripple is almost 88% of total thrust force. Because of this reason, designed LSM required an application of module phase set shift(MPSS) in order to reduce the thrust force ripple. Using design of experiments, Taguchi method, and approximate design, sub optimal design is established.
