In this paper, the working frequency band gap of ultrasonic motor (USM) was investigated under finite element model and experimental prototype. The findings indicate that the discrepancy between theoretical analysis and experimental test is mainly related to the fixation conditions of stator. This work proposes a new geometrical symmetrical stator for standing-wave-type linear USM to reduce the discrepancy. The first longitudinal and the second bending modes of stator are combined to drive the USM. Parameterized finite element model with actual boundary is developed to analyze and optimize the stator performance. The results show that the gap between working frequencies can be substantial reduced compared to the initial design.

A prototype for multi-mode linear ultrasonic motor has been proposed and designed. It is designed using a combination of the first longitudinal and the first bending mode. The piezoelectric ceramics convert energy using the longitudinal d33 effect which allows an improved reliability, large vibration amplitudes and excellent piezoelectric coupling. The normal direction motion of the driving element is excited by the first longitudinal mode. The tangential direction motion of the driving element is excited by the first bending mode. The resulting displacement of the driving element is transmitted by the frictional force between the vibrator and the rail in a linear motion. The analysis on the modals of the composite vibrator by using the ANSYS finite element software has been presented in this paper. Finally, the vibrator structure of the motor and the motor's own structures are designed. The basic design is discussed and simulations are compared with the experimental results, the results show that the motor characteristics can be optimized for a particular task by choosing the appropriate operating parameters such as exciting voltage, exciting frequency and normal force.
