Machine à commutation de flux à double excitation. Analyse des performances : Fonctionnement Alterno-Démarreur

This paper presents a study on a synchronous three-phase doubly-excited flux-switching machine that has been initially designed to work as a DC alternator with a nominal power of 3 kW. After presenting its structure, the electromagnetic performances are calculated using a 2D transient finite element model. The results have shown that the generated power can be easily controlled with the double excitation winding. This characteristic, together with a simple and robust rotor, make this machine very interesting for high speed embedded applications.
