摘要： A flywheel energy conversion device (10) provides highly efficient conversion between kinetic and electrical energy. The flywheel (10) produces increased output by providing armature coils (44) in an air gap (46) formed about the flywheel (both radial and axial embodiments are described). In preferred embodiments, field coils (30, 32) of a magnetic circuit are energized with DC drive current that creates homopolar flux within a rotating solid rotor (12) having teeth (14) 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 (14) passing across an armature air gap (46). Air gap armature coils (44) 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： Apparatus and methods for providing a pre-determined axial thrust force profile for use in a rotating machine that includes a magnetically permeable rotor with first and second surfaces and a generally perpendicular shaft is disclosed. One or more bearings support the shaft and a coil induces flux in the rotor. First and second pole pieces disposed adjacent to the first and second surfaces define first and second gaps. A series magnetic circuit including the pole pieces, the gaps and the rotor carries flux generated by current flowing in the coil. Pole pieces and gaps provide substantially similar reluctance in both gaps. Magnetic saturation characteristics of a series magnetic circuit may provide a pre-determined axial force profile as a function of coil current. A first magnetic saturation characteristic may provide a maximum axial force at a first current magnitude. A second magnetic saturation characteristic may provide a lower axial force at a current greater than the first current. The saturation characteristic may be formed by configuring the geometry and dimensions of the poles. The axial force profile may be formed to reduce the net axial thrust load on the bearings.

摘要： A flywheel energy conversion device (972) provides power in the event of a disruption in power from a primary source. The flywheel produces increased output by providing armature coils in an air gap formed about the flywheel (both radial and axial embodiments are described). The field coil of a magnetic circuit is energized with DC drive signal that creates homopolar flux within a rotating solid rotor having teeth cut from a flat disk. A monitoring system (970) monitors primary power and automatically varies said drive signal when said primary power is disrupted.
