行波型超聲波電機(jī)設(shè)計(jì)
摘要：超聲波電機(jī)是一種利用壓電陶瓷的逆壓電效應(yīng)工作的新概念、新原理電機(jī)。與傳統(tǒng)電磁型電機(jī)截然不同，其驅(qū)動(dòng)力矩并非由電磁感應(yīng)產(chǎn)生，它利用壓電陶瓷的壓電效應(yīng)使定子產(chǎn)生超聲波振動(dòng)，通過定子和轉(zhuǎn)子間的摩擦力來驅(qū)動(dòng)轉(zhuǎn)子。由于超聲波電機(jī)特殊的工作原理，它具有很多傳統(tǒng)電磁電機(jī)無法比擬的優(yōu)越性能，如結(jié)構(gòu)緊湊、低速大轉(zhuǎn)矩、響應(yīng)速度快、不受磁場(chǎng)影響、斷電自鎖、可直接驅(qū)動(dòng)負(fù)載等。正是由于超聲波電機(jī)具有許多的優(yōu)點(diǎn)和廣闊的應(yīng)用前景，成為當(dāng)前世界范圍內(nèi)的一門新興前沿課題。
本文主要以旋轉(zhuǎn)行波型超聲波電機(jī)為研究對(duì)象，設(shè)計(jì)制作超聲波電機(jī)的實(shí)驗(yàn)樣機(jī)。研究的主要內(nèi)容可概括如下：系統(tǒng)地總結(jié)國內(nèi)外超聲波電機(jī)的發(fā)展歷史和重要意義，介紹了超聲波電機(jī)的工作原理、分類、特點(diǎn)及其應(yīng)用前景。在對(duì)超聲波電機(jī)相關(guān)理論研究的基礎(chǔ)上，從超聲波電機(jī)定子設(shè)計(jì)著手，詳細(xì)介紹了超聲波電機(jī)的設(shè)計(jì)和制作過程。

Design of Traveling Wave Ultrasonic Motor
Abstract：Ultrasonic motor is a use of the inverse piezoelectric effect of piezoelectric ceramic work of new concepts, new principles of motors. Very different from the traditional electromagnetic motor, the driving torque is not generated by the electromagnetic induction, which uses the piezoelectric effect to generate ultrasonic vibration of stator, through the friction between the stator and rotor to drive the rotor. Since the working principle of ultrasonic motors special, it has a lot of traditional electromagnetic motors can not match the superior performance, such as compact structure, low speed high torque, fast response, free from magnetic influence, power locking, can directly drive the load and so on. It is because of ultrasonic motor has many advantages and potential applications, become the world's a new frontier subject.
      In this paper, a rotary traveling wave type ultrasonic motor for the study, designed the experimental prototype ultrasonic motor. The main content can be summarized as follows: The system sums up the history of the development of ultrasonic motor home and abroad and the importance of introducing the principle of ultrasonic motors, classification, characteristics and application prospects. In the theory of ultrasonic motors based on ultrasonic stator design from the start, ultrasonic motor described in detail the design and production process.
