    摘要： Axial magnetic bearings that include a primary winding(s) and one or more compensation windings that provide compensation such that operation of the first and/or second primary windings and the compensation windings results in a net magneto-motive force of around zero ampere turns. Current can selectively flow through one or both of the primary windings of an opposing pair of axial magnetic bearings, while current flows through the compensation windings in manner that compensates for the magneto-motive force generated by the primary winding(s). In at least situations in which the number of turns for at least one pair of compensation windings is generally equal to the number of turns of each primary winding, the net magneto-motive force generated by current flowing through a primary winding of one axial magnetic bearing and through the compensation windings of both axial magnetic bearings can generally be zero.

    摘要： A magnetic bearing which would reduce a leakage magnetic flux to be generated between teeth is provided. A predetermined one of its teeth (24) is configured so that a pitch (P1) between the predetermined tooth (24) and one of two adjacent teeth (24) that are located on clockwise and counterclockwise sides thereof in the circumferential direction is broader than a pitch (P2) between the predetermined tooth (24) and the other tooth (24) and that a magnetic flux flows in the same radial direction through the predetermined tooth (24) and the tooth (24) spaced from the predetermined tooth (24) by the narrower pitch (P1) but flows in two different radial directions through the predetermined tooth (24) and the tooth (24) spaced from the predetermined tooth (24) by the broader pitch (P2).

    摘要： A method of manufacturing an electrical machine includes selecting a desired threshold control current, selecting dimensions to modify stator teeth of a magnetic bearing based on the desired threshold control current, and modifying the stator teeth using the selected dimensions. A method of producing a rotating machine includes selecting an operating point of a magnetic bearing of the rotating machine, and shaping at least some stator teeth of the magnetic bearing to generate increased force at control currents above the control current at the selected operating point.

    摘要： A centrifugal compressor unit includes a driving means for rotatably driving a rotor, and at least one compressor including a statoric body and an arrangement of blade wheels mounted on a shaft which is rotatably driven by the rotor in the statoric body. The group formed by the motor and/or each compressor being mounted in a common housing is sealed from the gas used by the compressor. The compressor unit also includes an arrangement of active bearings for axially and radially guiding the rotor and the driven shaft, and a means for cooling the driving means and the guiding bearings by withdrawing the gas used by the compressor at the outlet of a first compression stage. The cooling means includes a set of internal conduits for supplying the driving means and the bearings with cooling gas. The cooling gas flow in the motor and the cooling gas flow in the bearing is separated and then converge upstream of the first compression stage.
