VERFAHREN UND ANORDNUNG ZUR ANSTEUERUNG DER TRAGWICKLUNGS- UND ANTRIEBSWICKLUNGSSYSTEME IN ELEKTRISCHEN MASCHINEN MIT MAGNETISCHER LAGERUNG SOWIE ELEKTRISCHER ANTRIEB

摘要

A method for the excitation of the radial force and torque winding systems of electrical drives with integrated magnetic bearings. The drives comprise an electrical machine with torque and radial force windings which are introduced in the stator or rotor, a position and angle sensor system and analog or digital electronic circuitry for the control, regulation, monitoring and feeding of the machine. A model is used for setting the rotor position (36,37) and the rotational angle of the rotor (phi) which describes the relationship between the forces acting radially and tangentially at the rotor or at the stator respectively and the loop currents, and indeed in such a manner that it takes into account the deviations from the sinusoidal form of the force components, which depend on the rotational angle of the rotor (phi).
