摘要

本研究提出、设计、制作并测试了一种跨尺度压电螺旋电机。该电机可以在准静态和谐振状态下工作，并通过模式转换实现跨尺度运动输出。电机由定子和转子组成，内部和外部有相同的螺钉。电动机的运动是通过定子和转子之间的摩擦来实现的。介绍了电机的结构和工作原理。通过有限元分析，研究了定子在不同模态下的振动模态。建立了电机的动力学模型。最后制作了样机，并对输出性能进行了测试。实验结果表明，在准静态模式下，最小分辨率为12.5 nm，最大负载能力为12 N。在谐振状态下运行时，样机向前旋转时，电机最大转速为10.4mm/min (32.8 rpm)，最大负载能力为30 N，最大效率为0.36%。电机倒转时，最高转速20.8 mm/min (65.5 rpm)，负载能力达到33 N，最高效率为0.46%。提出的压电电机促进了跨尺度作动器的发展。

Development of a type of cross-scale piezoelectric screw motor operating in quasi-static and resonant states

In this study, a cross-scale piezoelectric screw motor was proposed, designed, fabricated and tested. The proposed motor can operate in quasi-static and resonant states, and achieves cross-scale motion output through mode conversion. The motor is comprised of a stator and a rotor, with the same internal and external screws. The motor’s motion is achieved by friction between the stator and the rotor. Structure and working principle of the motor are introduced. The vibration modes of the stator in different modes were studied through finite element analysis. The motor's dynamic model was established. Finally, the prototype was fabricated, and the output performance was tested. Experimental results demonstrate a minimum resolution of 12.5 nm and a maximum load capacity of 12 N in quasi-static mode. When operating in resonant state, the motor achieves a maximum speed of 10.4mm/min (32.8 rpm), the maximum load capacity is 30 N and the maximum efficiency is 0.36 % when the prototype is rotated forward. When the motor is reversed, the maximum speed is 20.8 mm/min (65.5 rpm), the load capacity reaches 33 N, and the maximum efficiency is 0.46 %. The proposed piezoelectric motor promotes the development of cross-scale actuators.

期刊介绍： Mechatronics is the synergistic combination of precision mechanical engineering, electronic control and systems thinking in the design of products and manufacturing processes. It relates to the design of systems, devices and products aimed at achieving an optimal balance between basic mechanical structure and its overall control. The purpose of this journal is to provide rapid publication of topical papers featuring practical developments in mechatronics. It will cover a wide range of application areas including consumer product design, instrumentation, manufacturing methods, computer integration and process and device control, and will attract a readership from across the industrial and academic research spectrum. Particular importance will be attached to aspects of innovation in mechatronics design philosophy which illustrate the benefits obtainable by an a priori integration of functionality with embedded microprocessor control. A major item will be the design of machines, devices and systems possessing a degree of computer based intelligence. The journal seeks to publish research progress in this field with an emphasis on the applied rather than the theoretical. It will also serve the dual role of bringing greater recognition to this important area of engineering.
