    摘要： In rotating machine having a vertically oriented rotating shaft, a static magnetic force is used to simulate rotor weight and create the desired bearing preload. By installing a magnet the gravity based preload on the shaft journal bearings of a horizontal machine can be simulated for a vertical shaft. This can increase rotor stability, reduce the machine's vulnerability to hydraulically induced imbalance forces and give a more smooth transition through various shaft speeds.

    摘要： It is described a method for controlling a generator (115) having a rotor (104) with plural magnets (106) and at least a first stator winding (163) and a second stator winding (165), electrically separate from the first stator winding, the rotor being adapted to rotate, around a rotation axis (160) perpendicular to a radial direction (164), relative to the stator windings, the method comprising: allowing flow of a first electric current (154) through the first stator winding (163), thereby generating a first radial force (167) having a first magnitude and acting between the first stator winding (163) and the rotor (104); allowing flow of a second electric current (156) through the second stator winding (165), thereby generating a second radial force (169) having a second magnitude and acting between the second stator winding (165) and the rotor (104), wherein the first magnitude is different from the second magnitude resulting in a net generator generated radial force (170) generated by the first stator winding and the second stator winding at the rotor.

    摘要： An energy storage device according to an embodiment of the present invention stores electric energy generated by an electricity generation unit as rotational kinetic energy or supplies the stored electric energy to the electricity generation unit. The energy storage device may comprise: a rotation body having a rotary shaft; a housing having a bearing for rotatably supporting the rotary shaft and supporting or surrounding at least a part of the rotation body; and a buoyancy unit, a part of which is coupled to the rotation body and the other part of which is coupled to the housing, thereby generating power to buoy the rotation body. According to the embodiment of the present invention, the rotation body is buoyant and rotates by the buoyancy unit. Thus, it is possible to improve energy conversion efficiency by minimizing friction loss. Also, it is possible to minimize a cost increase as well as being applicable to bulk storage by simultaneously employing buoyancy by a mechanical bearing and a superconductor.

    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.
