Novel Generalised Notch Filter for Harmonic Vibration Suppression in Magnetic Bearing Systems

Yves Perriard, Leopoldo Rossini, Guzmán Borque Gallego, Douglas Martins Araujo

Magnetic bearings represent an important alternative to conventional ball bearings for applications that require very low noise and vibrations. The absence of contact and friction between rotor and stator parts, combined with the use of active vibration co ...

Efficiency Optimisation of Slotless Magnetic Bearing Machines

Yves Perriard, Leopoldo Rossini, Guzmán Borque Gallego, Douglas Martins Araujo

Efficiency is one of the key performance indexes in the design of electric motors. When considering fully active magnetic bearing machines, this aspect gain further relevance due to the necessity of actively controlling all the remaining degrees of freedom ...

Magnetic and Mechanical 3-D Modelling of a 15 T Large Aperture Dipole Magnet

Pierluigi Bruzzone, Douglas Martins Araujo, Luca Bottura

In 2018, two structures have been proposed with the goal of replacing the magnetEDIPOthat stopped operating in 2016. These two solutions were designed to generate a field of 15 T on an aperture of 100 x 150 mm2 at 4.2 K by using Nb 3Sn superconducting Ruth ...
