Abstract
A compressor arrangement for compressing fresh air for internal combustion engines includes a compressor wheel and an electric motor having at least one stator and at least one rotor having a rotor magnet and a rotor gap between the rotor and stator. The rotor gap is designed such that when the compressor wheel rotates, at least 50%, of the air mass flow to be compressed is fed through the rotor gap. The compressor wheel is mounted on a shaft or contains the shaft and at least one rotor magnet or a carrier for holding the rotor magnet and is mountable as a separate part on said shaft and may be bolted, splinted, glued, shrunk, or secured by form-fit to said shaft to prevent rotation.
