Abstract

The motor has a rotor shaft (2) that is provided at its axial end surfaces of connection areas for a form-fitting connection with a hub of a blower wheel. The wheel that drives cooling air flow has a blower blade formed for the motor. A stopper (3) is provided for the wheel for an axial locking and a centering device. A notch (4) receives a locking ring to axially lock the wheel, where the motor in the areas is designed such that dual curve of a profile has a circular form. A bore hole is provided at the surfaces, in which a straddle shaft of a transmitter is axially placed behind the blower.
