摘要： A turbo-generator machine for producing a supply of cooled air and a supply of electric power has a permanent magnet generator fixed to a shaft which is driven by a turbine rotor, the turbine serving to expand air which is supplied thereto. Magnetic bearings support the shaft radially for rotation about a precisely established axis while a magnetic thrust bearing keeps the shaft in a precisely fixed axial position. Power for the magnetic bearings is supplied by the turbo-generator during operation. Generator air gap is sized in coordination with the magnetic bearing air gap, and the generator stator and shaft are sized to minimize leakage flux from the generator to minimize interaction between the permanent magnet rotor and the magnetic bearings.

摘要： A composite-type electromagnet for a radial magnetic bearing has four composite-type electromagnet parts. Each part has four electromagnet cores formed of a magnetic material. The cores each have two protruding poles. A control coil is wound around each of the protruding poles and a biasing permanent magnet is disposed between each of the cores. The electromagnet cores and the biasing permanent magnets are in direct contact such that only a minute gap exists at a junction therebetween. A viscous material, adhesive material, or a magnetic fluid such as grease, having therein a material having high permeability and high saturation magnetic flux density is disposed in the minute gap so as to minimize magnetic flux leakage at the junction.

摘要： A flywheel energy conversion device provides highly efficient conversion between kinetic and electrical energy. The flywheel produces increased output by providing armature coils in an air gap formed about the flywheel (both radial and axial embodiments are described). In preferred embodiments, field coils of a magnetic circuit are energized with DC drive current that creates homopolar flux within a rotating solid rotor having teeth cut from a flat disk. The total reluctance of the magnetic circuit and total flux remain substantially constant as the rotor rotates. The flux may travel radially outward and exit the flat disk through the teeth passing across an armature air gap. Airgap armature coils are preferably utilized in which the changing flux density (due to the rotating teeth) induces an output voltage in the coils. The flux is diffused before returning to the rotor in one of several ways such that core losses are effectively reduced, thereby enabling the flywheel to operate efficiently at high frequencies.

摘要： A high speed electromagnetic rotating machine is arranged to avoid heat generation due to mutual inductance between a stator and rotor and has a stator provided with drive windings for generating a rotating magnetic field to rotate the rotor and position control windings fitted to the stator for generating a magnetic field having a different number of poles than that of the drive windings for controlling the axial or radial position of the rotor when an electric current sufficient to unbalance the magnetic field applied to the rotor by the drive windings is supplied to the position control windings. The rotor has a cage conductors interconnected to form a plurality of closed circuits mounted to the rotor, the closed circuits having a number of poles set so that there is no mutual inductance between the position control windings and the cage conductors. The cage conductors are connected by circumferentially-divided end rings rigidly connected by a retaining ring or by axially divided end rings directly connected to the rotor shaft. In one embodiment, the cage conductors are arranged in four-pole closed circuits, the drive windings have four poles, and the position control windings have two poles. In an alternative embodiment, the cage conductors may be arranged in two-pole closed circuits, the drive windings have two poles and the position control windings have four poles.
