 note = {application/pdf, An ultrasonic motor (USM) has a possibility to present the roughness and hardness of a virtual object because of its rapid response and large self-holding force. In order to change the preload of USM, the authors developed an ultrasonic actuator with a clutch function which can electrically control a preload. The electrical preload control gives variable reactions. From some experiments, it was confirmed that this actuator had a holding torque over wide range by the preload control and revolution speed and torque were controllable by either the clutch or USM.},
