Title:
磁気軸受を有する電気機械の軸支巻線および駆動巻線系を励磁するための方法および構造並びに電気駆動装置
Document Type and Number:
Japanese Patent JP4139444
Kind Code:
B2
Abstract:
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).
