Claim Text:
1. An electric machine for a hybrid or electric vehicle comprising a stator arranged within a rotor so that the rotor and the stator are concentric about an axis that extends in an axial direction, the rotor having a rotor carrier with a radially extending carrier section that extends substantially radially out from the axis and an axially extending carrier section connected to a radially outer region on the radially extending carrier section and extending substantially parallel to the axis, rotor plates mounted to a radially inner side of the axially extending carrier section and spaced axially from the radially extending carrier section and permanent magnets mounted to a radially inner side of the rotor plates and spaced axially from the radially extending carrier section, the stator having stator plates and wire windings, the wire windings forming winding heads that extend axially on both sides over the stator plates, and an impeller wheel connected to the radially extending carrier section of the rotor carrier and aligned axially with and facing the rotor plates and the permanent magnets, the impeller wheel further being arranged at a radial position radially inward of the axially extending carrier section and radially outward of the winding heads that are arranged on one axial side of the stator so that the impeller wheel does not project axially beyond the winding heads and does not project radially beyond the axially extending carrier section.
