A 200 000 rpm, 2 kW Slotless Permanent Magnet Motor

Yves Perriard, Pierre-Daniel Pfister

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 ...

Experimental evidence for a two-gap structure of superconducting NbSe2: A specific-heat study in external magnetic fields

Helmuth Berger

To resolve the discrepancies of the superconducting order parameter in quasi-two-dimensional NbSe2, comprehensive specific-heat measurements have been carried out. By analyzing both the zero-field and mixed-state data with magnetic fields perpendicular (H ...

Modélisation et commande du moteur piézoélectrique à onde progressive

Matteo Bullo

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 ...

Magnetic detector made on a semiconductive substrate

Pavel Kejik

Excitation circuit is formed by a single planar coil of an essentially square shape (9) with the magnetic core (10) in the f of a diagonal cross with the legs (101, 102) extending towards the corners of the square defined by the outer circumference (90) th ...

A novel planar magnetic sensor based on orthogonal fluxgate principle

Radivoje Popovic, Pavel Kejik, Franck Vincent, Ozge Zorlu

In this paper, we present a new planar fluxgate magnetometer structure. The sensor has the orthogonal fluxgate configuration which makes the detection part independent of the excitation mechanism. The sensor consists of a ferromagnetic cylindrical core cov ...
