This paper represents a numerical and experimental investigation of the multicell piezoelectric motor. The proposed design consists of three individual cells that are integrated into the stator, double rotor, and a preload system combined into a symmetrical structure of the motor. Each of the cells is characterized by a traveling wave and rotating mode motor. A finite element numerical analysis is carried out to obtain optimal geometrical dimensions of the individual cell in terms of generated vibrations and resonant frequencies of the structure. The results of the numerical analysis are compared with analytical calculations based on the equivalent circuit theory. Experimental tests are also presented, including laser interferometry measurements of vibrations generated at the surface of the stator, impedance analysis, as well as measurements of mechanical characteristics of the complete motor. The final stage of the study concludes that the presented motor can provide relatively high torque compared with other traveling wave rotary motors.

“…In addition, it has unlimited travel and a preload, which makes it self-locking. [15][16][17] The driving mode of the ultrasonic motor is relatively simple and may involve direct driving contact with a cylindrical or plane drive surface, or a rotating shaft output motor that has evolved from the linear standing wave motor. 18 The structure of the ultrasonic motor is shown in Figure 2.…”

Test as well as calibration precision of a coordinator is determined by the precision of the test turntable, and the improvement of the test turntable is the most effective way to improve the calibration accuracy of the coordinator. Therefore, it is of great practical significance and value to study a test calibration turntable which is suitable for a certain type of indexer. Based on the working principle of the ultrasonic motor, the mathematical model of the friction coupling interface is established; steady-state output force of the ultrasonic motor and the maximum angular velocity of the rotor are calculated; effect of the friction material type, magnitude of the pre-tightening force, and the rotor angular speed are analyzed on the maximum output force of the ultrasonic motor. The driving performance of the rotary table ultrasonic motor and the start/stop characteristic of the rotary table are studied. Finally, the driving ability of the ultrasonic motor is optimized and verified by experiments.
