In this work, a laminated ultrasonic motor operating in face expanding and face bending modes was designed, and a 5-layered ultrasonic motor prototype was fabricated and tested. By applying a sinusoidal electric field, the stator of the ultrasonic motor would produce the expanding/bending microscopic movement, then this microscopic movement was transformed into linear movement by friction force. Experimentally, the proposed ultrasonic motor revealed excellent performance under a relatively low driving voltage, where the maximum achievable output force and linear speed were respectively 1.5 N and 100 mm/s, under a sinusoidal driving voltage of 20 Vpp and 44.5 kHz. Compared with the previously reported ultrasonic motor, the proposed ultrasonic motor reveals many advantages, such as simple structure, excellent performance, and low driving voltage, demonstrating its promising applications in precise driving, high accuracy positioning, non-magnetic interference driving, etc.

以面扩展和面弯曲模式运行的叠层超声波电机
在这项工作中,设计了一种在面扩展和面弯曲模式下工作的叠层超声电机,并制作了一个 5 层超声电机原型并进行了测试。通过施加正弦电场,超声波马达的定子会产生膨胀/弯曲的微观运动,然后这种微观运动通过摩擦力转变为直线运动。实验表明,所提出的超声波电机在相对较低的驱动电压下表现出优异的性能,在 20 V pp的正弦驱动电压下,最大可实现的输出力和线速度分别为 1.5 N 和 100 mm/s和 44.5 kHz。与以往报道的超声波电机相比,所提出的超声波电机具有结构简单、性能优良、驱动电压低等优点,在精密驱动、高精度定位、无磁干扰驱动等方面具有广阔的应用前景。
