Abstract
A bolt-clamped Langevin transducer with segmented electrodes is designed and fabricated. This transducer can excite not only longitudinal vibration mode but also bending vibration modes. Therefore the ultrasonic motor using these two multi-mode Langevin transducers can excite necessary vibration modes for multi-degree of freedom motions. The diameter and the length of the transducer fabricated in this research is 15 mm and 25.4 mm, respectively. The structure, driving principle and application of the transducer are discussed.
