Modeling and optimization of ultrasonic linear motors

José Fernandez Lopez

Ultrasonic motors have received much attention these last years, in particular with regard to their modeling and their design principle. Their operating principle is based on piezoelectric ceramics that convert electrical energy into mechanical energy in t ...

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. ...

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 ...

Optimization of a new type of ultrasonic linear motor

Yves Perriard, José Fernandez Lopez

This paper presents the design, the properties, and the optimization study of a new type of ultrasonic linear motor. Numerical modeling has been carried out and simulations with software have been realized. To avoid performing a large number of simulations ...
