These drive, via gearing, an inner shaft 10 which is arranged around the drive shaft. The rotor of an electric rotational motor is arranged at the inner shaft, the rotor being surrounded by an armature 4 with poly-phase winding. The armature 4 is located between an inner and an outer housing part. The rotor windings are supplied with energizing current from sliding contacts, and the armature windings are connected to a braking unit.
