摘要

本研究提出一种直线超声马达。该结构是对称的，两组压电陶瓷(PZT-8)沿轴线排列。这种方式可以使电机结构紧凑。分析了该电机的工作原理。制作并测试原型以验证该原理的可行性。实验结果表明，在频率为29.96 kHz、电压为300VP-P的电信号激励下，电机的最大空载速度为1289mm/s。

A Linear Ultrasonic Motor Using Longitudinal Vibration

This study presents a linear ultrasonic motor. The structure is symmetrical and two groups of piezoelectric ceramics (PZT-8) are arranged along an axis. This way can make the motor structure compact. Operation principle of this motor is analyzed. Make and test a prototype to verify the feasibility of the principle. The experimental results show that the maximum no-load speed of the motor is 1289mm/s under the excitation of electrical signal with frequency of 29.96 kHz and voltage of 300VP-P.
