Patent number: 11750062Abstract: A drive device includes an electric motor and a gear unit that is driven by the electric motor. The electric motor has a laminated stator core which includes stator windings and is accommodated in a stator housing. The stator housing has recesses that are axially uninterrupted, i.e. in particular in the direction of the rotor shaft axis, and the stator housing is surrounded, especially radially surrounded, by a housing of the drive device, in particular a tubular housing and/or a cup-shaped housing, and the housing is set apart from the stator housing, in particular such that an especially circulating airflow is able to be provided within the housing, the recesses in particular guiding the airflow through in the axial direction, and the airflow being returned in the opposite direction in the set-apart region between the stator housing part and the housing.Type: GrantFiled: December 14, 2021Date of Patent: September 5, 2023Assignee: SEW-EURODRIVE GMBH & CO. KGInventors: Waldemar Becker, Domenik Hettel, Thomas Rung, Jens Schillinger
