Review on single-phase driven ultrasonic motors

Abstract

In recent decades, various single-phase drive ultrasonic motors have emerged, and only a single excitation signal is used in their working states. Single-phase driven ultrasonic motors have the benefits of most ultrasonic motors, as well as the advantages of a simple driving circuit construction, low cost, high design flexibility, and high reliability, among others. According to the working principles, they are divided into three types: the vibration mode alternating type, the vibration mode coupling type, the vibration mode converting type. This paper summarizes various types of single-phase ultrasonic motors. The three types of the working principles and its representative structures are explained; output performances of the single-phase ultrasonic motors are described; then, practical and potential applications of the single-phase ultrasonic motors are introduced; finally, the research of single-phase ultrasonic motors are reviewed, and its development prospect is prospected. This review is helpful for a comprehensive understanding of single-phase drive ultrasonic motors. This paper offers the groundwork for the development of a novel single-phase driven ultrasonic motor with improved mechanical output.

Low Profile Triangle-Shaped Piezoelectric Rotary Motor

“…State-of-the-art piezoelectric motors can solve complex motion or positioning problems in different technological and scientific fields via high motion speed and resolution as well as compact size. Moreover, the advantages of piezoelectric motors, such as magnetic field-free operation, gear-free direct drive of loads, and self-locking abilities make these motors highly attractive compared to electromagnetic or other types of motion sources [ 21 , 22 ]. On the other hand, complex driving schematics, high operation frequencies, as well as these motors’ lack of direct integration abilities with small devices limit their application [ 23 ].…”

Optimization of Ultrasonic Motor Control Based on NARX Neural Network

“…The experimental results indicate that the proposed method is feasible. Xu et al [2] analyzed single-phase driven ultrasonic motors and found that single-phase ultrasonic motors have multiple advantages, which are of great significance for optimizing single-phase ultrasonic motors. Sun et al [3] proposed a new method for optimizing the load design of ultrasonic motors and constructed an experimental platform for testing.…”

A Micro Radial-Torsional Vibration Ultrasonic Motor Driven by Single-Phase Signal

“…Therefore, researches on lightweight and high energy density motors suitable for vacuum space with low temperature and strong pressure has always been a hot spot. As a new type of friction drive motor, ultrasonic motor has compact structure, rapid response and no electromagnetic interference when working [5][6][7]. These merits meet the needs of stable and reliable operation under complex and harsh working conditions, and have become a focus of attention in recent years.…”
