Abstract: The present disclosure relates to a media gap motor for a turbocharger. The proposed media gap motor contains a rotor and a stator, wherein the stator comprises multiple fins which extend from an inner portion radially towards the rotor in a flow chamber formed between the stator and the rotor. The fins do not extend by means of their inner portions as far as the rotor, and therefore a gap is formed between an inner end of the fins and the rotor, wherein in internal diameter of the fins is at least 1.2 times and at most 3 times an external diameter of the rotor.

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.

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.

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.

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.

Abstract: The present invention relates to a compressor arrangement for compressing fresh air for internal combustion engines, comprising a compressor wheel (3) and an electric motor (4) having at least one stator (4b) and at least one rotor (4a) having a rotor magnet (4c) and a rotor gap between the rotor (4a) and stator (4b), the rotor gap being designed such that when the compressor wheel rotates, at least 50%, preferably at least 90%, especially preferably 100% of the air mass flow to be compressed is fed through the rotor gap, wherein the compressor wheel (3) is mounted on a shaft (8) or contains said shaft (3a) and at least one rotor magnet (4c) or a carrier (20) for holding the rotor magnet 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. Thus, an energy-saving and very fast-acting compressor for motor vehicles is provided that can particularly be produced on a large industrial scale, cost-effectively, and quickly.
