Comparison of the Single-phase Line-start Permant Magnet Motor's Transient Characteristics by Size and Position of Rotor Bar

영구자석 매입형 단상 유도 동기 전동기의 회전자 바의 크기와 위치에 따른 기동 특성 비교

The single-phase line start permanent magnet motor(LSPM) have a rotor cage bar for induction starting and permanent magnets, providing synchronous torque. So, LSPM is vary complex and difficult to analysis transient characteristics and rotor design. In this paper, F.E.M analysis about single-phase line start permanent magnet motor and compare of the single-phase line start permanent magnet synchronous motor's transient characteristics by size and position of rotor bar.
