  • Patent number: 8925666
    Abstract: A flywheel module has a closed housing with an opening, and an output which is formed by an output shaft that extends outward through the opening. A sealing ring is present between the output shaft and the boundary wall of the opening. A flywheel is accommodated in the housing, which flywheel is connected via a clutch to a first gear of a transmission whose other gear is connected to a first portion of a centrifugal disengaging clutch of which the other portion is connected to the output shaft. With this it be avoided that the flywheel starts to run at too high a speed, which guarantees the safety of the flywheel module.

    Abstract: Back in the nineteen seventies with the energy crisis. I thought There has to be other sources of energy in the world so I started to experiment with magnets and designed a magnetic generator, but the more I experiment with it I discovered that the earths magnetic field could interfere and also when a magnet gets hot it stopped being a magnet. So as time went on my Attion directed me to gravity. but the energy needed to pick Something up to drop it would be the same.

  • Patent number: 8212442
    Abstract: The Harmonic Accumulation and Relative Transference of Kinetic Energy method does not transmit, but rather, transfers torque/energy from a power source to a driven system of higher rotational speed through the use of an oscillating flywheel and a potential energy storage device, for example, a torsion spring The power source adds energy to the oscillating flywheel by applying an impulse torque to the flywheel just as the flywheel begins to start rotating, and then transfers that energy to the driven system when the flywheel's speed (which may be its highest rotational speed) matches that of the driven system's rotational speed and direction. Thus, the energy is transferred when the flywheel and the driven system are at 0 rpm “relative” to each other. Accordingly, the impulse torques may be applied using principles of electric motors.

With this configuration, when the front cover is deformed, stress applied to welded portions adjacent to the recessed portions can be suppressed since the fragile portions are easily deformed. Accordingly, even if the recessed portions are formed to the surface of a flywheel cover, stress can be prevented from being concentrated on the coupling portions of the flywheel cover and the sensor plate.

  • Patent number: 7425807
    Abstract: This disclosure relates to transient energy systems for supplying power to a load substantially instantaneously on demand. Transient energy systems may include a flywheel coupled the rotor of an induction motor generator. One embodiment of the disclosure refers to systems and methods for reducing loads on a bearing in a transient energy system. In another embodiment, the disclosure refers to an induction motor generator that is optimized for high power transient power generation, yet low power motor operation. Yet another embodiment of the disclosure refers to using a flywheel as a drag pump to cool components of a transient energy system. In yet another embodiment, a slip control scheme is discussed for regulating a DC bus. In yet a further embodiment of the disclosure a method is provided for reducing unnecessary turbine starts by making turbine start a function of the rotational velocity of a flywheel.

  • Patent number: 7365461
    Abstract: A crash management system for implementation in a flywheel energy storage system (FESS) is provided. Implementation of such a system entails designing an FESS rim that is highly failure resistant, and designing the FESS such that if one, some, or even all of its components fail, they are physically prevented from accumulating and releasing enough energy to cause rim burst, thus leaving the rim intact and capable of safely remaining spinning even after one or more FESS component failures have occurred.

  • Publication number: 20080047391
    Abstract: An auxiliary power supply includes a battery, a motor-generator and an inertial energy storage mass. The motor-generator draws power from the inertial energy storage mass to drive the motor-generator thereby creating electricity. As inertial energy is depleted from the drive mechanism during use, a battery recharges the inertial energy storage mass. The inertial energy storage mass includes a series of flywheels each having smaller disks contained therein. The disks translate radially with respect to the flywheels working with gravity to provide drive power to the motor-generator.

  • Patent number: 7302875
    Abstract: A hydraulic drive device, comprising a hydraulic motor (10), a rotating body (20) connected to the drive shaft (11) of the hydraulic motor (10), functioning, by itself as a flywheel, and having an internal gear (21) formed on the output side thereof, a rotation transmitting device (1) having a gear mechanism for transmitting the rotating force of the rotating body (20) to an output shaft gear (50) by allowing counter gears (30) to mesh with the internal gear (21) and the outer shaft gear (50) to mesh with the counter gears (30), and an output shaft connected to the output shaft gear (50). Whereby, since a variation in rotating speed of the hydraulic motor (10) can be absorbed by the rotation transmitting device (1), the hydraulic motor (10) can be used directly as the drive source of a vehicle such as a car and a truck.

  • Patent number: 7240583
    Abstract: An auxiliary bearing assembly for selectively engaging a shaft, preferably in an energy storage flywheel system, is configured to include a vibration damping seal, and an axial preload spring. The vibration damping seal damps out vibrations from the rotating group, following engagement of the auxiliary bearing assembly, while the rotating group is spinning down. The axial preload spring absorbs any differential thermal expansion or contraction that may occur between components.

  • Patent number: 7174806
    Abstract: A bearing damping system for damping vibrations and conducting heat from vibration-producing, heat-generating devices, an evacuated energy storage system including such a bearing damping system for damping vibrations produced by the rotating shaft and conducting heat from bearings and/or bearing assemblies; and a method for damping vibrations and conducting heat from vibration-producing, heat-generating devices. The bearing damping system includes one or more flexible bearing dampers in combination with one or more heat transferring rosettes. The heat transferring rosettes comprise a flexible thermally conductive member that transfers heat by conduction from the bearings, bearing assemblies and/or heat generating devices to a remote heat sink.

  • Patent number: 7066050
    Abstract: A life counter that calculates and records the life utilized of the flywheel in a flywheel energy storage system and indicates when it should be removed from service, based on operational history instead of monitoring for symptoms of failure. The life counter can effectively monitor and measure any or all of the flywheel energy storage system parameters, such as the flywheel structural life, vacuum system life, bearing system life and electronics life. The life counter ensures safe operation of highly stressed flywheels by indicating when the safety margin for the flywheel is reached so that the flywheel energy storage system can be removal from service prior to encountering a risk of catastrophic failure. In some cases, failures may not be preceded by measurable warning symptoms, so removal from service at a calculated end of life would be desirable.
