摘要： A flywheel energy storage device has a central shaft, a flywheel having a flywheel rotor supported by and mounted for rotation around said shaft, and a motor/generator having a stator and a rotor. The rotor is formed integrally with the flywheel rotor. The stator has an outer cylinder that is cooled by a liquid flowing in contact with its cylindrical surface. Preferably, the stator has (i) a cylindrical hub having an outer surface and longitudinal channels formed therein, (ii) a cylinder surrounding said cylindrical hub thereby providing passages through the channels, and (iii) end caps sealing the passages and providing a distribution channel for distributing fluid to said passages, thereby providing fluid cooling passages for said stator. A radial vibration dampener can be positioned at one or both ends of the shaft. The dampener has a plurality of spring members positioned between two cylindrical surfaces, one end of each spring member being attached to each cylindrical surface.

摘要： In an induction generator, an additional set of stator windings is provided, separate from and secondary to the main stator windings upon which the generator's output voltage is generated and supplied to the load. This separate stator winding is provided for the purpose of supplying the generator with the reactive electrical power it needs to maintain the rotating stator field and supplying any reactive power needed by the load. Thus, there is no need to use a capacitor assembly, for supplying the reactive power needed by the generator. Currents are injected into this separate winding in such a way that only reactive power is supplied to the generator. Specifically, a power measuring circuit measures the power in the additional set of stator windings, and a power error signal is formed by algebraically adding the outputs of the power measuring circuit. The power error signal is further processed and supplied as a timing control signal for generating the injected currents, which are maintained 90 degrees out of phase with an excitation voltage curve.

摘要： A power supply device for providing uninterrupted power for a period of time is disclosed. The power supply device has a controller and a flywheel device. The flywheel device has a housing that contains a flywheel rotor and a motor/generator rotor. The flywheel rotor and the motor/generator rotor are mounted on a common shaft. An active axial magnetic bearing is located to support the shaft for frictionless rotation. The bearing provides support for the shaft, the flywheel rotor and motor/generator rotor. The axial magnetic bearing is attached to the housing and provides, in combination with the motor/generator rotor, a flux path and magnetic field to exert a magnetic force to lift the motor/generator rotor and the shaft on which it is mounted.

摘要： Featured is a hybrid permanent magnet/homopolar power producing device and methods related thereto. The device includes first and second portions, the portions being arranged to have a common long axis and so one portion is moving with respect to the other portion. The first portion includes a stator, and a modulating field winding that generates a magnetic field responsive to a DC current therethrough. The second portion includes a support member having a mounting surface, a plurality of permanent magnets and steel poles affixed to the mounting surface, and being arranged thereon so as to form an alteration of steel and permanent magnet poles. The first and second portions and the support member are configured and arranged so each permanent magnet and each steel pole oppose a surface of the stator, so the permanent magnet flux passes between the permanent magnets, the stator and the steel poles, and so the magnetic flux generated by the modulating field winding emerges from each steel pole so as to selectively increase or decrease the permanent magnet flux. The first portion also includes a stator support structure and the first and second portions are configured and arranged so the stator support structure is spaced from the second portion support structure so the flux path between each permanent magnet and an adjacent steel pole is primarily circumferential and so the flux path for flux from the modulating field winding is primarily axial.
