Design Evolution of the Ultrasonic Piezoelectric Motor Using Three Rotating Mode Actuators

The development process and experimental investigation of the multicell piezoelectric motor is presented in this paper. proposed design consists three individual cells integrated into stator, double rotor, a preload system. Those elements are combined symmetrical structure motor. two new prototypes have been designed, simulated tested. Finite element numerical analysis carried out to obtain optimal dimensions cell terms generated vibrations resonant frequencies structure. results compared with analytical calculations based on equivalent circuit model. stator was manufactured using three-dimensional (3-D) printer alumide material. Finally, tests were conducted presented. Analytical, satisfactory agreement. Two exhibit torque-speed characteristics similar original while being cheaper easier manufacture.
