Unveiling the Rolling to Kayak Transition in Propelling Nanorods with Cargo Trapping and Pumping
Magnetic nanorods driven by rotating fields in water can be rapidly steered along any direction while generating strong and localized hydrodynamic flow fields. Here we show that, when raising the frequency of the rotating field, these nanopropellers underg ...
AMER CHEMICAL SOC2023Modal engineering of electromagnetic circuits to achieve rapid settling times
Inductive circuits and devices are ubiquitous and important design elements in many applications, such as magnetic drives, galvanometers, magnetic scanners, applying direct current (DC) magnetic fields to systems, radio frequency coils in nuclear magnetic ...
AIP Publishing2023Torque Computation With the Isogeometric Mortar Method for the Simulation of Electric Machines
Bernard Kapidani, Rafael Vazquez Hernandez
In this work, isogeometric mortaring is used for the simulation of a six-pole permanent magnet synchronous machine. Isogeometric mortaring is especially well suited for the efficient computation of rotating electric machines, as it allows for an exact geom ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Detection of Broken Rotor Bars in a Cage Induction Machine Using DC Injection Braking
In this paper, an effective procedure for broken rotor bar (BRB) fault detection in a three-phase squirrel-cage induction machine (SCIM) is proposed. This approach relies on a motor current signature analysis (MCSA) by observing the specific fault-related ...
IEEE2022Tree-cotree decomposition of isogeometric mortared spaces in H(curl) on multi-patch domains
Bernard Kapidani, Rafael Vazquez Hernandez
When applying isogeometric analysis to engineering problems, one often deals with multi-patch spline spaces that have incompatible discretisations, e.g. in the case of moving objects. In such cases mortaring has been shown to be advantageous. This contribu ...
ELSEVIER SCIENCE SA2022Novel Generalised Notch Filter for Harmonic Vibration Suppression in Magnetic Bearing Systems
Yves Perriard, Douglas Martins Araujo, Leopoldo Rossini, Guzmán Borque Gallego
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 ...
2021Impact of battery energy storage systems on the dynamic behavior of low-inertia power grids
The extensive deployment of non-synchronous generation determines lower level of grid inertia resulting in deteriorated frequency containment performance and abnormal frequency excursions in case of contingency. This calls for identifying assets, controls, ...
EPFL2021Three-dimensional electrodes for dielectrophoretic applications
This thesis reports the use of metal-coated three-dimensional SU-8 electrodes for dielectrophoretic bio sensing and particle manipulation applications. Placing free standing three-dimensional electrodes in microfluidic channels, electric fields can be appl ...
