Title
(DE) TURBOVERDICHTER
(EN) TURBO COMPRESSOR
(FR) TURBOCOMPRESSEUR
Abstract
(DE)
Bei der erfindungsgemäßen Ausführung handelt es sich um einen Turboverdichter, der zur Luftversorgung einer Brennstoffzelle geeignet ist, umfassend ein Gehäuse, eine Welle mit einem ersten und zweiten Ende, die gegenüber dem Gehäuse drehbar gelagert ist, und einer in dem Gehäuse angeordneten elektrischen Maschine, wobei die Welle mittels der elektrischen Maschine antreibbar ist. Zur Verbesserung des Turboverdichters wird vorgeschlagen, dass zur Lagerung der Welle ein erstes und ein zweites Lagerkonzept vorgesehen sind, wobei zumindest das erste Lagerkonzept eine Magnetlagerung umfasst, wobei zur Lagerung das Magnetfeld der elektrischen Maschine genutzt wird.
(EN)
The claimed embodiment relates to a turbo compressor suitable for supplying air to a fuel cell, said turbo compressor comprising a housing, a shaft which has a first and a second end and is rotatably mounted relative to the housing, and an electric machine arranged in the housing, wherein the shaft can be driven by means of the electric machine. In order to improve the turbo compressor, according to the invention a first and a second bearing concept are provided for bearing the shaft, at least the first bearing concept comprising a magnetic bearing, and the magnetic field of the electric machine being used for the bearing action.
(FR)
Le mode de réalisation selon l'invention concerne un turbocompresseur qui est approprié à l'alimentation en air d'une pile à combustible, comportant un carter, un arbre doté d'une première et d'une deuxième extrémité, lequel arbre est monté rotatif par rapport au carter, et un moteur électrique disposé dans le carter, l'arbre pouvant être entraîné au moyen du moteur électrique. L'invention vise à améliorer le turbocompresseur. À cet effet, un premier et un deuxième concept de palier sont prévus pour le montage de l'arbre. Au moins le premier concept de palier comporte un montage sur palier magnétique. Le champ magnétique du moteur électrique est utilisé pour le montage.
