ABSTRACT:
The rotor of a rotating-field machine is mounted to the rotor shaft via a cup-shaped hub which is attached to the shaft in a region thereof proximate to one of two bearings by means of which the shaft is journaled in a stator housing. An electronic control element annularly surrounding the rotor shaft is disposed partially within the rotor hub, an end portion of the control element projecting beyond the rotor hub and being mechanically connected to a stator located radially outwardly from the rotor. The stator and the control element are rotatably mounted in the housing and comprise respective segments which are removable for maintenance purposes through openings in a stator housing.
