  • Patent number: 8550793
    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.

  • Patent number: 8371121
    Abstract: A turbocharger includes a turbine wheel, a compressor wheel connected thereto, an electric motor situated on the side of the compressor wheel which is distant to the turbine wheel, and a rotor connected to the compressor wheel in a rotationally fixed manner and designed in a freely projecting manner. A drive system for motor vehicles includes a turbocharger. The turbocharger is characterized by a very spontaneous response behavior, as well as the possibility for energy recovery.

  • Publication number: 20110076167
    Abstract: An electric motor conveys media and includes a stator, a rotor with a rotor magnet, and a media throughput opening between the stator and rotor. An operationally reliable delivery of media at low cost and with low maintenance is achieved with the electric motor.

  • Publication number: 20110076166
    Abstract: A turbocharger includes a compressor arrangement for compressing fresh air for internal combustion engines, containing a compressor wheel as well as an electric motor with a rotor and stator. A rotor magnet of the rotor is designed such that it is partially or completely integrated into the compressor wheel, and the smallest diameter of the stator is 1.5- to 8-times the size of the largest outer diameter of the rotor. The turbocharger has a very spontaneous response behaviour in the transient range, as well as the possibility of an exact real-time regulation of the mass flow. It furthermore renders possible the energy recovery and this contributes to increasing the total efficiency.
