摘要:
The invention relates to a drive device, comprising an electric motor and a transmission driven by the electric motor. Said electric motor has a laminated stator core with stator windings which is accommodated in a stator housing. Said stator housing has axially penetrating holes, i.e. penetrating the housing in particular in the rotor shaft axial direction. The stator housing is surrounded, in particular radially surrounded, by a housing, in particular a tubular housing and/or pot-shaped housing, of the drive device. The housing is spaced from the stator housing, in particular such that a particularly circulating air flow within the housing can be produced. The holes in particular conduct the air flow in an axial direction and the air flow is recirculated in the opposite direction in the spaced region between the stator housing part and the housing.
