Máster Universitario Erasmus Mundus en Transporte Sostenible y Sistemas Eléctricos de Potencia
Nowadays, there is an increase in electric power consumption within the vehicles, which is predicted to soon exceed the generation capabilities of the traditional Lundell (claw-pole) alternator. Therefore, Research is focusing on other electric machines topologies, able to provide constant power over a wide range of engine speed, work both as a starter and an alternator and maintain a high efficiency, while not exceeding space limitations. The present thesis reports on the Axial Flux Permanent Magnet Machine with a Novel Mechanical Flux Weakening technique. The principle of operation is explained and a closed loop control for the flux weakening regulation is proposed. As a result, it is demonstrated through simulations that 10:1 constant power speed range can be attained, and possibly extended.
