Influence of Pole Arc and Salient Pole length on Torque of Salient Pole Rotor Type Single Phase SRM

회전자 돌극형 단상 SRM에서 극호와 돌극 길이가 토오크에 미치는 영향

The salient pole rotor type single phase SRM has a salient pole in the rotor in order to use axial direction fluxes and radial direction fluxes simultaneously. A flux linkage between the rotor and the stator are increased because of the salient pole in the rotor. But, the inductance at unaligned position and aligned position is increased together. Therefore, the length of pole are and salient pole should be selected that the inductance increment at aligned position is higher than the inductance increment at unaligned position. On this paper, we will be studied the influence of the pole arc and the salient pole length on the torque of the salient pole rotor type single phase SRM.
