Optimization of a Single Phase Ultrasonic Linear Motor

Yves Perriard, José Fernandez Lopez, Markus Flückiger

Piezoelectric ultrasonic motors are superior to electromagnetic micromotors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimization potenti ...

Sensorless Speed Control of Traveling Wave Ultrasonic Motor

Yves Perriard, Matteo Bullo, Markus Flückiger

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 ...
