 note = {application/pdf, The state of torque free does not exist in ordinal ultrasonic actuator because a stator vibrator is always preloaded to a rotor or slider, It is hard to arbitrarily change the preload of an ultrasonic actuator while operating. In this study, an ultrasonic actuator with clutch function, which can electrically control a preload, was developed by using piezoelectric actuators and mechanical amplifier, This ultrasonic actuator can have a wide dynamic range of torque. As a clutch function and high speed response were realized.},
