  • Abstract
    Longitudinal-torsional mode converters have greatly simplified the structure of ultrasonic motors using a combined torsional/ longitudinal vibration, making miniaturization more practical. A previous design of this type of motor used a multi-layer piezoelectric actuator. In this paper, we report on the performance of motors using wafer-type actuators. This motor design requires a reduced volume of piezoelectric material.
