Study on Implementing of an Ultrasonic Motor in Robotics

This paper aims the studying, modeling and testing of models of linear motors which use ultrasonic waves to achieve the movement. The studied motors are characterized by the positioning accuracy, small inertia, wide speed control (does not require gears and gearboxes), easy control, high torque per unit weight, miniaturization, simple structure, low noise, decreasing time-speed characteristic. Theme is nature transdisciplinary work, addressing elements of the electrical machines and electronics, electrical materials, mechanics, waves, computer and numerical methods, modeling of electromechanical systems and not least the technical and scientific creativity. Key-Words: Ultrasonic motor, linear motor, positioning accuracy, robotics, mobile element, stator vibrations
