摘要
超声波电机是一种利用压电陶瓷的逆压电效应使定子产生超声振动 ,并通过定子和转子间的磨擦来驱动转子运动的新型电机 ,工作原理不同于传统的电磁电机。本文简单介绍了超声波电机的发展历史及到目前为止超声波电动机的建模研究 。
Ultrasonic motor (USM) is a new kind of micro-motor that converts a piezoelectrically excited resonant vibration of the stator into a rotation movement of the rotor by frictional forces , its working principle is different from general electromagnetic motor. The paper reviews the development and modeling of USM, finally development respects for USM are stated.
