摘要

The device has an electric motor (5) arranged in a device housing (2) for driving the device. A cooling air inlet chamber (40) and a cooling air outlet chamber (50) are air-tightly separated from one another by an inner housing wall of the device housing. A motor housing (38) forms a distinct flow connection between the cooling air inlet chamber and the cooling air outlet chamber. A cooling air inlet port (42) and a cooling air outlet port (52) form a common port array in an exterior housing wall (41) of the device housing.
