    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: The present invention is an energy storage apparatus. The energy storage apparatus includes a stator that is stationary. The stator includes a winding encircling the stator for generating an output voltage. The energy storage apparatus also includes a rotor rotating relative to the stator. The rotor includes a plurality of magnets on a surface of the rotor adjacent to the stator. The rotor and stator include a gap between the magnets and the stator. The magnets are a source for the output voltage generated in the winding. The output voltage generated is dependent on the gap and the speed of the rotor. The energy storage apparatus uses centrifugal growth to regulate the output voltage.

    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.
