　In recent years, motors have been widely utilized in various industrial fields. Power converters such as the PWM inverter have been developed, and the requirements for a motor have varied. For example, the function of a motor for a robot, Factory Automation must include energy conservation, high precision position control and small size.　In addition, office automation machines used for research of rationalized business management and as information network terminals must offer small size, faster response time and high performance. The reluctance motor, which rotates digitally according to a pulse signal and boasts a sound basic system, a well developed rotor position sensor and high drive-system performance, has recently been the subject of a great deal of attention.In this paper, state equations describing the behavior of a reluctance synchronous motor are derived and found to be similar to those for a synchronous motor, A control system with internal angle feedback enable to operate without losing synchronism, A control strategy for obtaining high performance using three phase step drive are discussed. The applicability is confirmed from simulation results.
