Research overview:
We have proposed and fabricated for trial a new type ultrasonic motor that uses a longitudinal-torsional hybrid vibrator. With this motor,the torsional vibration is used to generate the drive force and the longitudinal one to regulate the transmission of the drive force, and they are controlled separately. A trial-made motor realized large torque for its small size. To realize the high performance ultrasonic motor, the transmission mechanism of the force and the optimum operating conditions are investigated.
