In this paper we analyze the mechanical characteristics of the single-phase-drive type ultrasonic motors. Though single-phase-drive type ultrasonic motors (USMs) has many merits against the multi-phase-drive type USMs, the research of them are not popular and the design method is not established yet. We simulated the static driving characteristics of the single-phase-drive type USM and cleared up the relationship between design parameters and T-N curve, output power and frictional efficiency. Finally we will show the adequacy of the simulations by conducting the driving tests.
