Abstract

An oil pump drive device () may include a housing (G), an oil pump drive shaft (AN), an electric motor, and a planetary gear set (RS). The planetary gear set (RS) may be supported by the housing (G) and have a first element (E) connected to a rotor (R) of the electric motor, a second element (E) connected to the oil pump drive shaft (AN), and a third element (E) drivable by a drive source located outside the oil pump drive device (). A first bearing (L) may be supported on the housing (G) and may support at least one of the elements (E, E, E) of the planetary gear set (RS) in a radial direction. The stator (S) of the electric motor is at least partially surrounded by a plastic mass (K), where the stator (S) is attached to the housing (G) via the plastic mass (K).
