Abstract

La présente invention concerne un turbocompresseur auquel est rattaché un accélérateur. Le turbocompresseur, qui est actionné par l'échappement d'un moteur à combustion interne et qui comprime et suralimente l'air d'admission, comporte, entre un carter de rouet et un corps de palier, un accélérateur servant à accélérer la rotation d'un rouet de telle façon que, pendant qu'une roue de turbine et un arbre sont mis en rotation par l'énergie de l'échappement, faisant ainsi tourner le rouet qui leur est relié, l'accélérateur reçoit la puissance de rotation provenant de l'arbre et du rouet et crée un couple par l'interaction des forces d'attraction et de répulsion d'un champ magnétique tournant créé par un module de rotor et d'un champ magnétique d'un module excitateur, transmettant ainsi une puissance avec un régime et un couple accrus. Ainsi, un débit accru d'air comprimé présentant une pression de suralimentation plus élevée est fourni, permettant une réactivité d'accélération améliorée à travers toute la plage de conduite.
