Abstract
A Halbach array is radially disposed in an environment optimized for efficiency and controlled for efficient generation and use of power in order to generate, establish, and maintain a desired level of rotational energy with enhanced efficiency.
Claims20
Apparatus for generating rotational energy by means of manipulation of magnetic fields, the apparatus comprising:
- a rotational energy generator in which a central shaft is integrally joined with one or more rotors, each said rotor having, at or near its most distant radial points, a permanent magnet array, said permanent magnet array comprising one or more mounted permanent magnets of sufficient quality to maintain and radiate a steady magnetic field following repeated exposure to alternating magnetic fields, said permanent magnet array further adapted to travel radially within a circular track housed within a stator, said rotational energy generator further being adapted with transmission means for output rotational energy power to be delivered to a target consumptive facility;
- said circular track being adapted to provide housing and electrical communication for an electromagnet array, said electromagnet array comprising one or more electromagnets which may be regularly spaced so as to be proximate to the permanent magnets of said permanent magnet array as it rotates about said shaft and radially about said track;
- each said electromagnet being adapted with an electromagnetic core, each said electromagnetic core being further adapted with material and dimensions so as to permit said electromagnetic core to rapidly develop, sustain and enhance a magnetic flux created when an electric current is passed through an inductive coil about said electromagnetic core, and then to rapidly lose said magnetic flux when said electric current is switched off from said inductive coil, and to further be capable of rapidly reversing said magnetic flux orientation when said electric current is reversed through said inductive coil or passed through an alternative reversing electric coil;
- each said electromagnet being in electrical communication with a power supply, said power supply further comprising an electrical storage component capable of storing and releasing small bursts of electrical current as may be directed from one or more switches, said power supply being selected from any component known to have the capability of reliably storing and releasing said electrical energy in small and precise bursts, said power supply further being adapted to receive electrical energy in small amounts and to reliably and efficiently store said electrical energy for release, and said power supply further adapted to receive and transform said power from said power generator output for any other desirable source into a proper form for power supply storage;
- and
- controlling means for managing and controlling the storage and release of electrical energy to achieve optimal timing and quantity of the delivery of electric current from said power supply to each said circumferential electromagnet, said controlling means further comprising sensors detecting and communicating the rate of rotation of said generator shaft, the position of each said permanent magnet, and any other data useful in determining the optimal times for release of said bursts of electric current and the amount of current to be released in each said burst of electric current, receivers to receive input signals from said sensors, and relays and switches adapted to facilitate said current release.
