In this study, the application of non-uniform thickness piezoelectric ceramics on ultrasonic motors is studied. Since the present non-uniform thickness piezoelectric ceramics are mainly used to ...

Goodwood, Motor Circuit, Chichester PO18 0PH; When you think of Goodwood, most will think of star-studded events like the Festival of Speed – but you can also visit during the rest of the year too.

According to the automotive supplier, the electric motor rotor temperature sensor (eRTS) delivers significantly more precise measurement results than the current software-based temperature simulation, ...

Abstract: A rotary ultrasonic motor using bending vibration transducers is proposed. In each transducer, two orthogonal bending vibrations are superimposed and an elliptical trajectory is generated at ...
