Abstract
The invention relates to an electrically operated charge-air compressor, for connection to an internal combustion engine, which includes an electric motor with a stator and a rotor for driving a compressor impeller; the compressor impeller is disposed in a compressor housing that is provided with at least one air inlet and one air outlet, and the air inlet and the air outlet communicate via a flow conduit extending in the compressor housing, and by rotation of the compressor impeller in a compression portion of the flow conduit, a compression of the charge air is attainable. It is proposed that the charge-air compressor be refined such that the compressor impeller can be displaced in the compressor housing out of a working position into a position of repose and back again, and the compressor impeller upon a displacement into the position of repose is moved at least partway away from the compression portion.
