Ultrasonic Motor's Reliability

Reliability of Ultrasonic Motor.

In the development of ultrasonic motors, the following themes should be systematically studied:

• Measuring methods for high-field electromechanical couplings.
• Materials development (low loss and high vibration velocity).
• Piezo-actuator designs. (Heat generation mechanism ,Degradation mechanisms,New multilayer actuator designs)
• USM designs (Displacement magnification mechanisms (horn, hinge-lever),USM types (standing-wave type, propagating-wave type),Frictional contact part.)
• Drive/control (High frequency/high power supply,Resonance/anti-resonance usage.
