회전자 형상에 따른 단상 SRM의 특성 해석

Characterisitic Analysis of Single Phase SRM Considering Rotor Shape

SRM has a characteristic of a robust, simple structure and wide operating ranges. So, recently it has studied and developed in many kinds and forms with the technology of power electronics and analysis and design by use of computer. Also, It is used in a very wide range of industrial applications. In particular, single phase switched reluctance motor has a merit in practical use because it has simple operating drives and control systems, very high energy density per unit volume comparing with three phase SRM. But it must have a starting device. In this paper, the shapes of the single phase SRM rotor are designed to reduce the torque ripple, to improve the efficiency.
