Electric motor comprising pressing cooling air conveyance and method for cooling components of the electric motor

An electric motor comprising:

• an electronics housing in which motor electronics are accommodated,
• a stator bush for accommodating a stator, the stator bush being arranged axially adjacent to the electronics housing,
• a cooling impeller is arranged axially between the stator bush and a rotor, the cooling impeller being driven by the rotor, wherein
• a fluidically connected axial through-channel is provided in the stator bush and a fluidically connected axial through channel is provided in the electronics housing, a cooling air flow generated by the cooling impeller being conveyed through the channel through the stator bush and through the electronics housing, and
• the cooling impeller formed as a radial fan wheel having a blade geometry with a forward curvature such that, in normal operation of the electric motor, direction of the cooling air is such that the cooling air is drawn in a radially direction from outside into a peripheral radial air inlet of the cooling impeller and the cooling air is conveyed into and through the through-channel in an axial direction and exits axially from the electric motor.
