Design and Simulation of a Piezoelectric Ultrasonic Micro Motor
piezoelectric ultrasonic micro motor. This work aims to study various aspects of the stator of a piezoelectric ultrasonic micro motor using COMSOL Multyphysics 4.2a. The building model of piezoelectric ultrasonic micro motor is shown in Fig. 2 and the simulated model of the stator is shown in Fig. 3.

Trial Construction and Operation of an Ultrasonic Vibration
As is well known, very little research work has heretofore been conducted for developing a high power electric motor driven by an ultrasonic vibration driving system. This paper describes a principle according to which ultrasonic vibration can be converted to rotary movement in one direction, and proves theoretically that our new and unique

An ultrasonic motor is a type of electric motor formed from the ultrasonic vibration of a component, the stator, placed against another, the rotor or slider depending on the scheme of operation rotation or linear translation .
New construction of loudspeaker for low frequency range by
tion of a vibration by revolution of an ultrasonic motor. It was given by use of an ultrasonic motor with a heavy metal block on its shaft. The preliminary model with this construction radiated a satisfactorily large sound. However, use of large metal block prevents reduction of loudspeaker size as well as weight.
