The Optimum Design of The Permanent Starting Device used in The Single-Phase SRM

단상 SRM에 사용되는 영구자석 기동장치의 최적 설계 I

Generally a single-phase SRM(switched reluctance motor) has several stator and rotor poles but these are excited by one regulated current at the same time. It has only one inductance variation. It means that the positive torque is only generated in the positive slope of the inductance variation. The single-phase SRM can not be started by itself. The single-phase SRM can be started by itself if the rotor is placed in the positive slope of the inductance variation. Then, the starting device is required to place the rotor in the starting position before start. On this paper, the equation of the force requisite for the starting device is derived using by the frictional force of the rotor
