Abstract
An exhaust gas turbocharger for a drive device, having a compressor that is capable of being electrically supported or driven by a media gap motor, the media gap motor having a rotor that is operatively connected to a bearing shaft of a compressor impeller of the compressor, and having a stator that surrounds the rotor at least in some regions in the circumferential direction relative to an axis of rotation of the bearing shaft. A power electronics for controlling at least one electrical winding of the stator surrounds the axis of rotation at least in some regions in the circumferential direction, a cooling jacket that stands in touch contact with the stator and/or with the power electronics being provided for cooling the stator and/or the power electronics.
