摘要：

This paper presents a short cylinder ultrasonic motor, which is featured by its new structure and novel excitation mode. The stator is composed of two piezoelectric disks and two short cylindrical blocks in which the disks are sandwiched by the blocks to form a special bolted Langevin type transducer. The corresponding vibrations are utilized to produce the driving force. A novel excitation mode is realized which can solve the problem of instability occurred in the conventional excitation mode. By using finite element analysis, the vibration pattern and driving mechanism are simulated. Finally, the proposed motor and its driving circuitry are prototyped to experimentally verify its validity and performance.
