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 magnetic bearing system has magnets for producing magnetic fields, and a member which carries loop portions of electrically conductive material. The member and magnets are relatively rotatable about an axis of rotation so that the loop portions travel along a prescribed circular path relative to and through the magnetic fields. The magnetic fields subject the loop portions to magnetic flux to produce electromotive forces in the loop portions when the loop portions deviate from the prescribed circular path. This induces an electrical current in the loop portions. The direction of this electrical current is such that, in the presence of the magnetic fields, Lorentz forces are exerted on the loop portions and the loop-carrying member in directions which are lateral with respect to the circular path. To avoid undesired current flow when the member is rotating on its prescribed axis, at least the first and second loop portions are electrically interconnected to form a closed loop. The interconnected loop portions are circumferentially spaced from each other and they lie in circumferentially spaced magnetic fields.

摘要： An alternating current electromagnet is used in a magnetic bearing in which one or more electrically conductive loops travel on a prescribed path through a magnetic field produced by the electromagnet. An electrical current is induced in the loop whenever it deviates from its prescribed path. A power supply drives the electromagnet(s) at a frequency at which the magnetic field interacts with the currents induced in the loop to force a deviant loop laterally toward the prescribed path. Capacitors may be connected in series with the loops to provide them with the desired reactances.

摘要： A continuous power system assembly is provided that includes an integrated shaft-driven unit. The unit contains a turbine, an alternator, a flywheel and a feed pump, all of which are coupled to the shaft. During various modes of operation, any of the turbine, alternator or flywheel may provide the torque used to drive the shaft. When the alternator is not providing the necessary torque to drive the shaft, it is operated as a generator that provides back-up power to a load. The present invention also includes a unique nozzle design that improves the ease with the nozzles may be manufactured in comparison to known designs. The nozzle is manufactured as two halves which are mated as part of the manufacturing process. The individual nozzles may, because only half of the nozzle segments exist on either half of the nozzle block, be easily manufactured using conventional machining.

摘要： Uninterruptible power supplies are provided that utilize a material to provide a source of thermal energy that may be converted to electrical energy to produce backup electrical power for a load. In some embodiments, a hot tank assembly is utilized to hold a liquid heated to a predetermined temperature. A closed-loop pipe containing, water for example, is immersed in the heated liquid. Upon the loss of primary power, the water flows into the heat exchanger where it is raised above its boiling temperature. The steam is then passed to a heat engine (e.g., a turbine-based system) that converts the heated steam to mechanical energy by causing the heat engine rotor to rotate. A generator is physically coupled to the heat engine so that the rotation of the heat engine rotor drives the generator. The generator produces AC power which is converted to DC and again back to AC before being provided to the load. In other embodiments, a solid mass, such as a block of iron, is heated to a predetermined temperature. The heat from the solid material is then converted to electrical energy for the load.

摘要： An uninterruptible power supply (UPS) system supplies power to computers, medical apparatus or other critical loads when primary power supply falters. The UPS system includes an electrical machine connected to a turbine that can be rotated by a motive fluid from a fluid supply. The electrical machine can be a dual purpose electrical machine (a motor/generator) or a two unit machine (one motor and one generator in a single housing or in separate housings) connected to the turbine. When power is supplied from the primary power supply to the critical load, the electrical machine acts as a motor to rotate the turbine and energy is stored by the turbine rotor in the form of rotational momentum. When power from the primary power supply falters, the rotational momentum of the turbine rotor initially rotates the electrical machine which acts as a generator to provide power to the critical load. If the power loss or failure is extended, the turbine motor is driven by combustion products, steam, compressed gases or other motive fluids to maintain the rotary motion of the turbine and the generator. Numerous methods and apparatus are also described for reducing system losses and improving overall efficiency.
