Definitions

  • the present disclosure which can be variously embodied as, for example, a method, apparatus, or the like, relates to the use of kinetic energy for the conversion of energy from electrons in the environment into electrical energy in the form of either alternating current (AC) or direct current (DC) in a manner which reduces electromagnetic drag, thereby greatly improving conversion efficiency.
  • Various exemplary embodiments can provide, for example, a geometric design and electrical excitation sequencing of rotors associated with an electric machine such that significant positive motor effects can be realized in addition to the improved electric generator efficiency, which motor effects can be constructively used.
  • the working efficiency factor however is far from an ideal 100% conversion efficiency factor and gains can be made from reducing friction, improving magnetic coupling and the like. Still further gains can be achieved using superconducting technology.
  • a superconducting generator can be around 10-times smaller than a conventional generator f— or the same output.
  • Every atom has a nucleus composed of positively charged protons and uncharged neutrons. Negatively charged electrons orbit the nucleus. In most atoms, the number of electrons is equal to the number of protons in the nucleus, so there is no net charge. If the number of electrons is less than the number of protons, then the atom has a net positive charge. If the number of electrons is greater than the number of protons, then the atom has a net negative charge.
  • a wire connected to a DC power source will cause electrons to flow through the wire in a manner approximating water flowing through a pipe.
  • the path of any one electron can be anywhere within the volume of the wire or even at the surface.
  • an AC voltage is applied across a wire it will cause electrons to vibrate back and forth in such a manner as to generate magnetic fields that push electrons toward the surface of the wire.
  • the frequency of the applied AC signal increases, the electrons can be pushed farther away from the center and toward the surface.
  • An electric power generator contains two main parts: a stator and a rotor.
  • the stator is generally made of laminated iron or other ferro-magnetic material and contains long slots having a certain depth and in which wire coils can be wound in such a fashion to allow electric power to be generated when magnetic fields emanating from the rotor move past the coils.
  • the rotor contains a specific arrangement of magnets, which can be generally wound armature electro-magnets whose strength is governed by the amount of current flowing in the armature windings. When the rotor spins inside the stator, the magnetic fields from the rotor induce a current in the stator windings thus generating what is referred to as electrical power.
  • the energy required to spin the rotor is typically supplied by a drive unit of some kind, such as an electrical drive motor, diesel or other fossil fuel motor, steam turbine or the like. At typical efficiencies, only 20% of the energy input by the driver motor is devoted to creating electric power. The remaining 80% is dissipated by magnetic drag, or braking forces, that develop between the rotor and the stator.
  • a magnetic force or braking force is created by the flow of the load current in the generator conductors that opposes the rotation of the generator armature. If the load current in the generator conductors increase, the drag associated with the reaction force increases. More force must be applied to the armature as the load increases to keep the armature from slowing. Increasing drag and increasing load current leads to decreasing conversion efficiency and can eventually lead to destructive consequences for generator equipment.
