Abstract:
Method for the excitation of radial force and torque windings of an electromagnetic rotating machine having a stator, a rotor and an integrated magnetic bearing, the method comprising geometrically shaping the torque and radial force windings, introducing the windings in the stator or the rotor so that only a non-sinusoidal magneto-motive force or flux distribution is produced, providing a position and angle sensor system and therewith measuring a rotor position and a rotational angle of the rotor, and supplying the radial force and torque windings with phase currents depending on the rotational angle of the rotor so that resulting forces caused by the phase currents act radially and tangentially at the rotor or at the stator, respectively, substantially independently of the rotational angle of the rotor.
