An external rotor motor, especially for driving fans, including a stationary inside stator, an outside rotor, and a stator-lamination pack of the inside stator having a central bore into which there is installed, with the aid of a clamping seating, a stator bushing which is connected mechanically on one side with the motor flange carrying the external rotor motor. Inside the stator bushing, there is a turnable shaft which is fixedly secured, on the side lying opposite the motor flange, within a rotor bushing of the turnable outside rotor. The motor flange includes on the inside, a hollow cylindrical added piece with an inward-directed annular crosspiece, which abuts against the stator-lamination pack. The stator bushing, installed with the aid of a clamping seating in the central bore of the stator-lamination pack, has an outward-directed annular crosspiece which is seated against the inward-directed annular crosspiece of the cylindrical added piece of the motor flange. |
