A Haptic Interface with Motor/Brake System for Colonoscopy Simulation

Hannes Bleuler, Evren Samur, Lionel Flaction

Training for colonoscopy, which is the examination and treatment of the colon, is often performed on real patients once the physician has passed the novice level. This increases the risk to the patient and lengthens the procedure time. Since a decade ago, ...

Conception of a Piezoelectric Micromotor

Ultrasonic Motors are drive systems used in a lot of industrial applications notably because of their advantages i.e. no audible noise, compact size and fast response. Therefore, this technology has been chosen for the design of a new type of actuator for ...

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 ...

A Five-Phase Two-Motor Centre-Driven Winder with Series-Connected Motors

Drazen Dujic

Application of power electronics in variable speed electric drives enables utilization of ac machines with a phase number higher than three. It then becomes possible to use the additional degrees of freedom, available in multi-phase systems, to control oth ...

Comparative study and selection criteria of linear motors

Samuel Chevailler

Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...

Optimization of Electric Motor for a Solar Airplane Application

Yves Perriard, Patrick Ragot, Miroslav Markovic

This paper presents a method to model and optimize brushless dc motor for a solar airplane. In order to obtain the optimal solution for the given specifications, all free parameters are analyzed globally in one go. For this, the commercial optimization sof ...

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. ...

A contribution to energy saving in induction motors

Electric motors consume over half of the electrical energy produced by power stations, almost the three-quarters of the electrical consumption in industry and almost the half of commercial electrical consumption in developed countries. Motors are by far th ...

Innovative standstill position detection combined with sensorless control of synchronous motors

Jan Persson

Sensorless control of PMSM's (Permanent Magnet Synchronous Motors) has occupied scientists for a long time. The result of this research is becoming widely accepted by the industry due to its low cost and reliability. However, the majority of today's motor ...
