Patent ID: 7781926

Claim:
An electric motor, comprising: a stator; a rotor including a rotor shaft; a bearing support including a bearing seat for a B side bearing of the rotor shaft; and a housing including at least one first mechanical interface adapted to connect to the bearing support; wherein the bearing support includes a further interface adapted to connect directly to a bottom part, the bearing support forming a cup-shaped housing for a brake and a fan and extending beyond the brake and the fan in an axial direction away from the B-side bearing, the cup-shaped housing terminated on one end by the B-side bearing and the rotor shaft and terminated on an opposite end by an approximately planar grating, the terminated cup-shaped housing enclosing the brake and the fan, the bottom part having an interface adapted to connect to a cover, the bottom part forming a housing for at least power electronics, heat from the power electronics dischargeable one of (a) directly and (b) at least indirectly to the bottom part, the bottom part thermally conductively connected to the bearing support to discharge the heat of the power electronics by the bearing support to surrounding air.
