piezo discsPiezo Disc Application:
Aerospace, satellite communications, and navigation.
The researchers developed a new three-degree-of-freedom piezoelectric ultrasonic motor.
The concept of this design is to include a spherical rotor between two piezoelectric transducers.
Each sensor is attached to a flange, which works like a single structure.
This transducer is designed to increase the amplitude of the vibration,
producing higher torque and driving force for the three-dimensional rotational motion of the spherical rotor.
The proposed USM can be used for humanoid robots, optomechanical systems, or small satellites.
The USM is made up of multiple components and is lightweight and reliable.
They verified the feasibility of the driver through numerical analysis and experimental research, found a suitable resonant frequency, and optimized the shape of the flange.
The researchers obtained the results of numerical analysis through experimental studies and verified the working principle of the piezoelectric motor.
Today, piezoelectric devices are very common in a wide range of commercial and industrial fields.
