Progress on the Design of the 15 T Magnet of the EDIPO Test Facility

Pierluigi Bruzzone, Kamil Sedlák, Roberto Guarino, Evgeny Solodko

EDIPO 2 (the upgraded EDIPO test facility) will provide a unique testbed for superconducting cables for fusion magnets,accelerators, and other applications. Compared to the previous magnet assembly, the magnetic field is enhanced from 12.35 T to 15 T, the ...

Buckling instabilities and spatio-temporal dynamics of active elastic filaments

Tobias Schneider

Biological filaments driven by molecular motors tend to experience tangential propulsive forces also known as active follower forces. When such a filament encounters an obstacle, it deforms, which reorients its follower forces and alters its entire motion. ...

Electrical effects in winding of large electrical ac machines application to advanced large size DFIM

Frédéric Michael Maurer

To meet the electrical grid's demand on pump power variation, GE Renewable Energy develops since 10 years variable speed machines (also called Doubly Fed Induction Generators or DFIG). Within turbogenerators, the phenomenon of circulating currents in Roebe ...

Two Full Parameter Identification Methods for Synchronous Machine Applying DC-Decay Tests for a Rotor in Arbitrary Position

Jean-Jacques Simond, Mai Tu Xuan, Frédéric Michael Maurer

The main obstacle to a wide use of dc-Decay tests lies in the necessity to align the rotor with the d- or q-axis, which is very difficult to perform for high-power units. The goal of this paper is to propose and validate standstill dc-Decay measuring metho ...

Potential of Flex-PCB Winding in Coreless Tubular Permanent Magnet Synchronous Machines

Yves Perriard, Bruno Dehez, François Baudart

Many applications are limited by the performance of the motors that power them. In the small power range, slotless BLDC motors are commonly used due to their intrinsic high power density and smooth torque characteristic. However, recent work has shown that ...

Contribution to the Ultra-Fast Charging of Electric Vehicles : The Configurable Modular Multilevel Converter (CMMC)

Rosa Martel Danoary Tsirinomeny

It is generally agreed that one of the drawbacks of a conventional vehicle is the inability to always reach the best operating point of the engine and the inability to regenerate the kinetic energy. Meaning, even with the help of the gearbox or automatic t ...

Optimization of the force and power consumption of a microfabricated magnetic actuator

Herbert Shea, Juan José Zarate

The force (F) and the power consumption (P ) of a magnetic actuator are modeled, measured and optimized in the context of developing micro-actuators for large arrays, such as in portable tactile displays for the visually impaired. We present a novel analyt ...

Modular multilevel battery packaging for a universal and flexible EVs charging system

Rosa Martel Danoary Tsirinomeny

Electric Vehicles (EVs) carmakers are heavily confronted by the limited fault ride-through capabilities of actual EVs battery packs. Therefore, this paper introduces a new method of EVs battery packaging based on modular multilevel battery modules as well ...

Real-time 3D thermal modeling of a magnetically levitated planar actuator

Yves Perriard

A transient thermal model used to monitor the temperature distribution in real-time in a long-stroke moving-magnet planar actuator is presented. The temperature distribution in the stator coils of the planar actuator depends on the trajectory of the levita ...

Contribution to the Active Generator Principle : the Gate-commutated Polyphased Matrix Converter

Antoine Béguin

This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...

Analyse et mise en oeuvre d'un moteur électromagnétique microfabriqué

Sebastiano Merzaghi

Until now, the preferred solution for MEMS (Micro Electro Mechanical Systems) actuation is the electrostatic one. The main reason is that this kind of actuators can be easily manufactured following the microfabrication rules, as their geometry perfectly fi ...

Optimization design of a segmented Halbach permanent magnet motor using an analytical model

Yves Perriard, Miroslav Markovic

We present an optimization design of a slotless permanent-magnet brushless dc motor (400 W, 6000 rpm), with two-segment Halbach arrays. The optimization is based on a motor analytical model which is obtained by solving the magnetic scalar potential using t ...
