摘要： In axial magnetic bearing apparatus in which a rotary disc made of a magnetic material is fixedly attached to a rotating shaft, and electromagnets are disposed on opposite sides of the rotary disc so as to have suitable very small distances therefrom respectively, so as to bear the rotating shaft axially in a non-contact state, a deep groove for forming an air layer having large magneto-resistance is provided all over the outer circumference of the rotary disc. Thus, formation of a magnetic circuit not contributing to position control is relieved, and the weight of the disc is reduced so that the position control performance of the axial magnetic bearing and the natural frequency of a rotor are improved.

摘要： A system for pumping or mixing a fluid using a levitating, rotating pumping or mixing element and various other components for use in a pumping or mixing system are disclosed. The pumping or mixing element is placed in a fluid-containing vessel in close proximity to a superconducting element. A cooling source thermally linked to the superconducting element provides the necessary cooling to induce levitation in the pumping or mixing element. The superconducting element may be thermally isolated, such that the pumping or mixing element, the vessel, and any fluid contained therein are not exposed to the cold temperatures required to produce the desired superconductive effects and the resulting levitation. By using means external to the vessel to rotate and/or stabilize the pumping or mixing element levitating in the fluid, including possibly rotating the superconducting element itself or moving it relative to the vessel, the desired effective pumping or mixing action may be provided.

摘要： A flywheel power source having a flywheel supported by a bearing system for rotation inside an evacuated container. A brushless motor and generator is coupled to the flywheel for accelerating and decelerating the flywheel for storing and retrieving energy. The generator has a rotor coupled to the flywheel, and a stationary stator wound using multiple-strand individually insulated conductor wire coils. A heat energy transfer system passively cools the stator by heat transfer from the stator to an unpumped liquid coolant surrounding the coils and in intimate contact with the conductors in the coils. The stator is mounted in a stator coolant vessel that is partially filled with the coolant. The liquid coolant limits the maximum temperature of the coils during discharging of the flywheel power source.

摘要： The invention relates to a magnetic bearing assembly of a rotor in a stator, with at least one magnetic bearing (1) comprising a stator part (2) and a rotor part (3) arranged coaxially thereto in the operating position without contacting the stator part. The bearing effective area of the rotor part is formed by a radial exciting system (6) having a permanent magnet (4), while the stator part (2) comprises a high-temperature superconductor concentrically surrounding the radial exciting system (6) while maintaining an annular air gap (10). For increasing the specific rigidity of such a bearing, it is proposed according to the invention that the high-temperature superconductor is divided in at least two HTSC partial shells (7, 8) which, after the transition into the superconducting state, can be displaced against one another by an actuator (12) in the radial direction from a position in the hot state of the bearing, in which each HTSC partial shell (7′, 8′) has a first radial spacing (k) from the radial exciting system (6), into a working position with a second, smaller radial distance (operating gap (0)from the radial exciting system (6).

摘要： A gas turbine engine (10) is provided with a plurality of shafts (18, 19, 20) interconnecting its compressor portions (11, 12, 13) with its turbine portions (15, 16, 17). Each shaft (18, 19, 20) is supported in the hotter part of the engine by electromagnetic bearings (26, 28, 32) and by rolling element bearings (24, 27, 29, 31, 33) in the remainder of the engine (10). The arrangement provides a simplified liquid lubrication system for the rolling element bearings (24, 27, 29, 31, 33) which reduces the likelihood of lubricant thermal degradation of the lubricant.

摘要： The present invention is directed to a blood pumping system that includes two portions, including a pump portion capable of use inside a living body and a drive portion for disposition outside the living body. The drive portion includes a pump drive system, including an assembly configured to cause the impeller to rotate in addition to an assembly configured to levitate the impeller. The present invention includes two separate versions of the pump drive system, including a first embodiment having a high temperature superconductor to levitate the impeller into a predetermined and substantially translationally fixed position spaced from said pump housing, and a rotating, motor driven magnet system to cause the impeller to rotate, and a second embodiment that incorporates a rotating superconductor, which will both levitate and rotate the impeller. Each embodiment of the pump drive system includes a cryostat vessel in which the superconductor is disposed for confining the superconductor in a liquid nitrogen environment to therefore maintain its temperature at 77 K in order to cause the superconductor to levitate magnets within the pump.

摘要： An improved gas circulator for a gas-cooled nuclear reactor system is disclosed which includes a stator, a rotor having a rotor shaft, and an impeller attached to one end thereof. A radial active magnetic bearing and a radial backup bearing are positioned proximate each end of the rotor shaft. An axial active magnetic bearing is also located between the ends of the rotor shaft, as is an axial backup bearing, with two of the backup bearings enclosed within a sealed chamber that may contain a lubricant, for example, a solid lubricant or a liquid lubricant. Preferably, the gas circulator is installed in a nuclear reactor system with the rotor shaft in a substantially vertical orientation and the sealed chamber near the bottom of the rotor shaft. The lower radical backup bearing and the axial backup bearing are advantageously located within the sealed chamber. The lower radial backup bearing and the axial backup bearing may be spaced apart sufficiently to permit the lower radial backup bearing to provide substantially all radial support for the rotor when the radial active magnetic bearings are deenergized.
