Abstract
A drive device has a transmission housing with an external rotor-type electric motor. The electric motor is coupled to the transmission and is actuated by a motor electronic unit. The electric motor has a stator and a rotor which circulates about the stator and is connected to a drive shaft that is guided through a stator bushing with a first sleeve section for holding the stator bushing in the transmission housing in a rotationally fixed manner and with a second sleeve section. A groove frame insulation which surrounds the stator teeth in the axial direction is placed on the second sleeve section. An annular element which is arranged between the first sleeve section and the groove frame insulation and which has a joint element is placed on the second sleeve section of the stator bushing. The joint element engages into a joint contour of the first sleeve section.
