Synopsis

This book provides a completely up-to-date survey of the many different types of ultrasonic motors currently in use. These motors, which use ultrasonic vibrations to produce a frictional driving force, have many attractive features, including simple structures which can easily be miniaturized, large power to weight ratios, high torque at low speed, high precision due to low inertia and easy electronic control, and no associated magnetic field. With such advantages, they are increasingly displacing conventional electromagnetic motors in robot actuators, camera autofocus mechanisms, and aerospace devices, to name a few examples. Written by leading experts on the subject, the book introduces the reader to the design and manufacture of the motor as well as to techniques for evaluating motor performance. It will be an invaluable guide to electrical engineering researchers, designers, and manufacturers.

A propos du livre

Présentation de l'éditeur

An ultrasonic motor uses ultrasonic vibrations (usually in a piezoelectric material) to produce a frictional driving force. This entirely new motor type has many attractive features: BL a simple structure which can easily be miniaturized, BL large power to weight ratio, BL high torque at low speed (reducing the need for gearboxes), BL high precision due to low inertia and easy electronic control, BL no associated magnetic field It has many actual and potential uses, in many cases displacing conventional electromagnetic motors: robot actuators, consumer goods (e.g. camera autofocus mechanisms), precision actuators (used in e.g. semiconductor manufacture), and aerospace devices. This book provides a completely up-to-date survey of the many different types of ultrasonic motor practically realised. It gives information on the design and manufacture of the motors as well as techniques for the evaluation of performance. It wil be an invaluable guide to this novel Japanese invention for researchers, designers, and manufacturing engineers.
