Abstract
An electric motor construction is provided with a planetary gear system, including an annular thin-rimmed stator () as well as a torque takeoff shaft () concentric relative thereto. The construction includes inside the stator () an annular thin-rimmed rotor (); a sun gear () fixedly coupled to the rotor and concentric with the takeoff shaft (); an intra-rotor immovably coupled ring gear () with a toothed inner surface; planet gears () meshing with the ring gear and the sun gear; a planet carrier () that the planet gears are supported on; as well as a coupling arrangement () for transmitting torque of the rotor optionally directly or by way of the planet carrier to the torque takeoff shaft.
