Model Identification of Traveling Wave Ultrasonic Motor Using Step Response
Ultrasonic motor’s model adapting to control application is the foundation of the motor’s high performance control. Ultrasonic motor’s frequency-speed control model gives a signification to improve speed control performance. This paper shows the design of stepping response experiments, and also explains the model identification of USM by the way of characteristic point method. Considering its t...

متن کاملA finite volume method and experimental study of a stator of a piezoelectric traveling wave rotary ultrasonic motor.
Piezoelectric traveling wave rotary ultrasonic motors are motors that generate torque by using the friction force between a piezoelectric composite ring (or disk-shaped stator) and a metallic ring (or disk-shaped rotor) when a traveling wave is excited in the stator. The motor speed is proportional to the amplitude of the traveling wave and, in order to obtain large amplitudes, the stator is ex...

متن کاملA Traveling Wave Ultrasonic Motor Using Polymer-based Vibrator
Having natures of low speed, high torque and quick response characteristics, ultrasonic motors (USM) are applied in robot, precision machine and optical instruments. A lightweight actuator is essential to decrease the total weight and increase the operability. Although USMs, in general, are superior to conventional electromagnetic motor in torque/weight ratio, lighter motor is demanded. In this...
