Sensorless Speed Control of Traveling Wave Ultrasonic Motor

Yves Perriard, Markus Flückiger, Matteo Bullo

Ultrasonic motors are a good alternative to electromagnetic motors in medical robotics, since they are electromagnetically compatible. Estimating speed instead of using encoders reduces cost and dimension of the robot on the one hand and increases reliabil ...

Sensitivity Analysis and Optimization of a Standing Wave Ultrasonic Linear Motor

Yves Perriard, José Fernandez Lopez

This paper presents the sensitivity analysis of an ultrasonic linear motor using design of experiments (DOE) and the finite element (FE) optimization of its deformation amplitude. A first ultrasonic linear motor prototype has been built at the laboratory. ...
