Large-scale heat pumps can contribute towards the decarbonisation of district heating
systems and industrial processes. Unidentified faults can have a negative impact on the …

Piezoelectric inertia motors—also known as stick-slip motors or (smooth) impact drives—use
the inertia of a body to drive it in small steps by means of an uninterrupted friction contact. In …

A piezoelectric rotary ultrasonic motor is modeled for the purpose of predicting, a priori,
motor performance as a function of design parameters. The Rayleigh-Ritz assumed mode …

Piezoelectric ultrasonic motors are driven by tangential stresses in the interface between
stator and rotor. These stresses are generated by the elliptical motion of the material points …

Piezoelectric motors are used in many industrial and commercial applications. Various
piezoelectric motors are available in the market. All of the piezoelectric motors use the …

This is the first book devoted to a systematic description of the linear theory of piezoelectric
shells and plates theory. The book contains two parts. In the first part, the theories for …

In many ultrasonic applications frictional effects play an important role (eg ultrasonic
machining, ultrasonic motors). For optimising the applications in terms of quality, efficiency …

A multi-degree-of-freedom (DOF) ultrasonic motor consisting of a bar-shaped stator and a
spherical rotor was developed. It can generate 3-DOF rotation of the rotor around …

A self-moving ultrasonic actuator (SUA) that operated by the longitudinal traveling wave and
possessed high carrying/towing capability is developed in this article. The SUA is …

The first success in the operation of an ultrasonic linear motor at HF band driving frequency
using the Rayleigh wave is described. The substrate material is a 127.8/spl deg/Y-cut …
