The invention relates to a method for producing a control device (1) for mechanically controlling a component. The control device may have a device housing (2) including a motor accommodating space (3) in which an electric motor is arranged. The electric motor (4) may include a motor housing (5) having a stator (6) and a rotor (7), the rotor including a rotor shaft (8). The method may include selecting an electric motor from a plurality of electric motors each suitable for a specified application. Each of the plurality of electric motors may have a different respective axial motor length (11)and may have a same respective motor cross section (12). Further, the method may include adapting the motor accommodating space (3) to the respective axial motor length (4) of the selected electric motor.
