Contribution au Dimensionnement Optimal d'Alternateur à Griffes Sans Aimant - Apport des alliages FeCo

Abstract : Claw-pole alternators are often used in automotive industry. Permanent magnets like NdFEB are currently integrated to increased the power density of claw-pole machine. However their higher price brings into question their usage. This tight context implies finding new technical solutions to keep the same power density without NdFeB magnets. The solution adopted consists to evaluate the potential of gain with different soft magnetic materials and more especially FeCo family (AFK18, AFK1 et AFK502). Their higher price imposed us to use FeCo just at the core of the alternator but we have also evaluate their usage at the rotor. This work is based on an adapted design methodology including two modeling level (magnetic equivalent circuit model and finite element model) in order to obtain a good compromise between time computation/accuracy. Several studies have been made with, as a first step, the identification of new core geometry customized for FeCo core. As a second step, a study comparing output current according to FeCo used at the core is presented, rotor is optimized only. As a third step, is exposed the global optimization of the alternator with an AFK502 (rotor and stator optimization with a study on the optimal poles pairs number) in order to identify the maximum output current gain with an FeCo core. Finally, the last study compare output current according to FeCo used at the rotor, rotor and stator are optimized .
