  • Patent number: 10720815
    Abstract: Various embodiments associated with a segmented magnetic core are described. The segmented magnetic core can be made up of multiple singular structures so as to allow an individual singular structure to be removed with ease and without disturbing another magnetic core. This modular core design allows for a significant reduction in motor housing weight due to compatibility of the design with lightweight materials and the potential absence of extensive housing when so designed. This modular core design can be incorporated into a motor or a generator and this modular core design can be accomplished, in one example, by way of stacking and/or interlocking employing low cost assembly. In one example, a motor or a generator uses sensors to detect an operational failure in a magnetic core, notifying a user early of the failure.

  • Patent number: 8994245
    Abstract: The permanent magnet type electrical rotating machine has an overhung rotor support structure in which a shaft of a rotor is supported at only one end side thereof by a bearing provided on one side of a casing of the electrical rotating machine. Another end side of the rotor shaft to be a bearing support-free side is capable of being joined to an end of a shaft of a prime mover via a flange formed at an end of the shaft. The rotor shaft is configured such that, upon a state of not being coupled to the prime mover shaft, the flange on the bearing support-free side is joined to an end face of the casing through a retaining member to be prevented from moving in any of an axial, radial and circumferential directions of the rotor shaft.

    Abstract: The OPEN thermodynamic system for vehicles must have these main ingredients, Every drive shaft, Axle or wheels that are a moving major part of the vehicle must have the components of the 3 phase generator system to create a rotating magnetic field with a stator to harness the clean electric power by converting the natural mechanical kinetic energy that all vehicles create when they move. Every drive shaft, Axle or wheel is a generator because they have all of the 3 phase generator components to make electricity from mechanical kinetic energy. These generator systems can be sized to fit any vehicle and they can create from 0 to 300 KW of clean electricity or more. This present invention will advance vehicles by using 100% of the mechanical kinetic energy to convert it into clean 3 phase electricity. The Closed system for vehicles uses the components that cannot harness or convert anything.

  • Publication number: 20150048703
    Abstract: A system for generating and recovering energy comprising an electric generator integrated with a consumer's utility provider's network to generate electrical energy. Electrical power is transmitted from an electric power grid to a control box at a location requiring energy (e.g., home or business) via a bidirectional meter which measures power delivered by and to the power grid. The control box powers an AC driver which feeds a load to and controls the speed of a motor. A torque multiplier multiplies a first torque output from the motor to produce a second torque output which is fed to an alternator. The power generated by the electric generator is transmitted to a remote location for consumption. In one embodiment, exported energy is returned to the utility provider in exchange for credit against the consumer's account or for payment. In an alternative embodiment, the present invention functions as an independent power plant.

  • Publication number: 20150021913
    Abstract: A method and an apparatus are provided for initiating rotation of blades of a wind turbine when wind speed is less than a cut-in speed. A solar powered wind turbine apparatus includes a solar dome with photovoltaic cells, operably connected to a rotor assembly, and an electric motor. The photovoltaic cells convert solar energy from incident sunlight into electrical energy. The electric motor electrically connected to the photovoltaic cells rotates the blades of the rotor assembly using the electrical energy from the photovoltaic cells. The electric motor powered by the photovoltaic cells initiates the rotation of the blades of the rotor assembly when wind speed is less than the cut-in speed, and therefore reduces or eliminates the cut-in speed required to rotate the blades. The blades of the rotor assembly thereafter continue to rotate in response to a force of wind on the blades and/or the powered electric motor.
