Introduction Ultrasonic motors (USMs) convert electrical energy into mechanical energy based on inverse piezoelectric effect and achieve actuation via friction [1], [2], [3]. The combined slider can achieve a larger output because of the double driving feet and sliders. Finally, an experimental platform is built and the mechanical characteristics of the motor are experimentally investigated. Study on Linear traveling Wave Ultrasonic Motors. The motor prototype contains a stator and dual sliders. Hence, a finite element analysis (FEA) of the proposed structure was undertaken here using the commercial FEA software ANSYS 17.0. But in this case many other questions arise: The electromechanical behavior of the individual motors differs slightly, the motor characteristics are strongly dependent on the driving parameters and the driven load, many applications need some extra power for special cases like overcoming higher forces periodically. An exceptionally high-torque 'hybrid transducer' ultrasonic motor uses circumferentially-poled and axially-poled piezoelectric elements together to combine axial and torsional vibration along the contact interface, representing a driving technique that lies somewhere between the standing and traveling-wave driving methods.

Some of the earliest versions of practical motors in the 1970s, by Sashida,[1] for example, used standing-wave vibration in combination with fins placed at an angle to the contact surface to form a motor, albeit one that rotated in a single direction. The most obvious difference is the use of resonance to amplify the vibration of the stator in contact with the rotor in ultrasonic motors. Since the silver coating is located on the left and right sides of the two PZT ceramics, the right (left) side potential of the left (right) PZT ceramics is zero.
