A drive unit for an aircraft ground wheel associated with a brake unit for braking the ground wheel includes: a driving motor drivingly coupleable to the ground wheel; and a cooling system including at least a drive cooling unit configured to generate a drive cooling air stream for cooling the drive unit and a brake cooling unit configured to generate a brake cooling air stream by sucking in air from the brake unit. A method of controlling such drive unit in which the cooling system is driven by the driving motor of the drive unit includes: decoupling the driving motor from the ground wheel and increasing the rotational speed of the driving motor to increase the amount of generated drive cooling air, when an operating condition of the ground wheel and/or of the drive unit is switched from a propulsion mode to a non-propulsion mode.

Drive unit for aircraft landing gear with integrated cooling

An electric drive unit for a motor vehicle comprises an electric motor having a motor housing, a stator mounted in the motor housing and having coil-wound poles, a rotor arranged internally of the stator with an air gap present between the stator and the rotor, and a planetary gear system having a sun wheel, a planet carrier, planet wheels and a ring gear. The planet wheels have a maximum diameter and axial positioning that an imaginary common envelope cylinder for all maximum diameters of the planet wheels is located radially inside of the winding heads present on one axial side of the stator and axially beside the portion of the rotor adjoining the air gap and that the planet wheels project in axial direction outwardly beyond said winding heads either not at all or with less than 50% of their tooth width in engagement with the sun wheel.
