The surprising influence of continuous alternating electric current on recrystallization behaviour of a cold-rolled Aluminium alloy

Roland Logé, Cyril Cayron, Ke Huang

Pronounced acceleration of recrystallization in cold worked metals is generally observed during annealing with additional high density electric current pulses. In this work, continuous alternating current of low density was applied to heat cold-rolled samp ...

Validation by Measurements of a Windage Losses Model for Very-High-Speed Machines

Yves Perriard, Douglas Martins Araujo, Guillaume Paul-André Burnand

When designing a very-high-speed (VHS) machine, it is crucial to evaluate the windage losses accurately, because they are an important part of the total losses. It is therefore important to validate a reliable model, further used for the design and optimiz ...

Two Novel Methods for Parameter Identification of Synchronous Machine Using DC-Decay Test with Rotor in Arbitrary Position

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

The goal of this paper is to propose and validate standstill DC-Decay measuring methods for a rotor in arbitrary position. The first new method (DC-Decay I) delivers the equivalent circuit with a few measurements. The second new method (DC-Decay III) permi ...
