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 ...
Component minimized multi-machine drives have recently become an area of much research interest. One such drive comprises two three-phase induction motors supplied by a five-leg voltage source inverter (VSI). With only five legs available to supply two thr ...
This paper presents the analysis of inductive links for remote powering of implantable devices and a method to improve the power link efficiency by modifying the geometrical parameters of planar spiral inductors. The analysis of the inductive links include ...
To improve the resolution of the Very Large Telescope Interferometer (VLTI) a two-stage mechanical system, a so called Differential Delay Line (DDL), is developed jointly by the EPFL and the Observatory of Geneva. The system is designed to reach nanometer ...
Micronozzles with piezoelectric actuator were fabricated and investigated. The micronozzles were fabricated in glass substrates using a powderblasting technique, and the actuator is a bimorph structure made from a piezoelectric polymer. The actuator was lo ...
In high energy physics and space applications it becomes mandatory to solve specific problems concerning the power supply. In both cases, it exists a harsh radiation environment and the presence of external electromagnetic perturbations. The former prevent ...
The paper presents the development of a very high speed (200 krpm, 2 kW) slotless permanent magnet motor, using an analytical model. The multiphysics analytical model allows a quick optimization process. The presented model includes the magnetic fields, th ...

The objective of this Master Project is the modelisation, simulation and optimisation of a mechatronic system with Matlab/Simulink. The mechatronic system comprises the following parts: three-phase Brushless DC motor, driving electronics and mechanics. The ...
In large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a multi mobile system is proposed. It consists of s ...
