Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Functional Magnetic Resonance Imagery (fMRI) is an imaging technique allowing the observation of brain activity. Haptic interfaces can be used in conjunction with fMRI to stimulate the subject while measuring brain activity. Using robotic stimulation over ...
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 ...
In haptics, the forces to be displayed vary widely in terms of magnitude and bandwidth. A single actuator can hardly comply with these requirements. It has thus been proposed to combine electrical motors and passive devices in a hybrid actuator to cover a ...
This paper describes a novel and patented air-gap monitoring system for large low speed synchronous hydro-generators. This new system is based on inductive sensors, it is able to measure in real time a static or a dynamic rotor eccentricity, a stator or a ...
Piezoelectric motors are particular motors converting electrical energy into mechanical movement, based on the inverse piezoelectric effect. Piezoelectric material, when electrical field applied, produces acoustic or ultrasonic vibrations. These vibrations ...
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 ...
This paper presents a method to detect the position of a linear actuator without any position sensor. The actuator winding has a resonance frequency that is very related to the position of the linear actuator Pmoving part. A sinusoidal scan voltage is supe ...
This paper reports a new MRI (Magnetic Resonance Imaging) compatible actuator that can operate near an MRI without degrading its imaging quality. A high-power electrostatic motor is introduced and its MR-compatibility is examined, both experimentally and t ...
Piezoelectric motors are resonant vibromotors. They represent a new actuator generation in the field of servo-drives. In particular, the travelling wave ultrasonic motor presents a high torque at low speed, a zero speed torque without feeding, low sensitiv ...
This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...
