This paper describes details of this method and its application to a reluctance structure scroll actuator in which the dynamic characteristics and the static torque were compared with the measured results in order to verify the appropriateness of the method. The paper also outlines the analysis of a high-speed rotation PM disc structure scroll actuator that was carried for performance comparison with the reluctance structure scroll actuator in terms of static torque, dynamic torque, and output characteristics. The results appear to indicate that the reluctance structure can achieve high torque in the low-speed range, and the PM disc structure on the other hand enables high-speed rotation while its torque is low.
