Abstract :
Low power driving method, namely, energy circulation drive of surface acoustic wave (SAW) motor is reported here. The maximum no-load speed and the maximum output force were 0.82 m/s and 3.4 N when the driving power was 20 W. The driving power was only a half of non-circulation drive for same performances. Mechanical output power of the actuator was estimated to be 0.62 W.
