Every claim in the granted motionless electromagnetic generator patent is a claim to a thing — a generator comprising a magnet, a core, coils. This continuation claims the same disclosure as a method: not the apparatus but the sequence of driving current alternately through two input coils so that each pulse opposes the permanent magnet's flux in its own path, and taking current from the resulting swings in two output coils. The shift matters more than it sounds, because it is what lets the self-running arrangement be claimed as a procedure rather than as a box. Claims four through six set that procedure out in order: start the switching and control circuit from an external source, rectify one part of the output to drive that circuit thereafter, rectify a second part to a load, and take the two parts from the two different output coils. The application was filed in February 2002, published in March 2004, and abandoned.

Why it matters hereChapter 6 already teaches the device. This document is what the inventors were trying to protect once they had it: the operating procedure and the feedback arrangement, stated as the steps a builder would follow rather than the parts a builder would buy — which is the form a reader needs if they want to know what was actually being proposed, as distinct from what was measured.

What it claims

01The independent method claim states the operating sequence as a procedure: drive current alternately through a first and second input coil wound on two U-shaped magnetic structures that run between the opposite poles of a permanent magnet, so that the current in each coil produces a field opposing the concentration of the magnet's flux in its own path, and take induced current from an output coil on each path. Nothing turns, and the magnet is never overpowered.Claim 1
Settled physics
02The self-driving arrangement is claimed as four ordered steps rather than as a circuit diagram. The switching and control circuit is driven by an external power source during starting; a first portion of the output current is rectified to form a first rectified output; the switching and control circuit is then driven by that first portion once starting is complete; and a second rectified portion flows through an external load, with the two portions taken from the two different output coils. That is the whole of the self-running proposal, in the order a builder would perform it.Claims 4, 5 and 6
Designed, not yet built
03The materials and timing are claimed as limitations on the method, which is where the engineering specifics sit. Each U-shaped structure may be a nanocrystalline magnetic alloy, either a cobalt-niobium-boron alloy or an iron-based one; the input coils are alternately driven for periods of approximately 11.5 milliseconds; and the flux changes are required to occur without driving either path to magnetic saturation. Staying below saturation is the condition that keeps the switching cheap.Claims 7 to 11
Settled physics
04A second independent claim covers the stacked geometry as a method. Two spaced-apart plate sections, each around an aperture, are joined by posts and permanent magnets alternating around the ring, so every post sits between a pair of magnets and every magnet between a pair of posts, with all the magnets aligned the same way. An output coil goes on each post; the input coils sit on the plate sections between a magnet and a post and are wound to oppose the flux through themselves, in two groups driven alternately. Two further claims fix whether both groups sit on the upper plate or one on each.Claims 12, 13 and 14

Abstract

An electromagnetic generator without moving parts includes a permanent magnet and a magnetic core including first and second magnetic paths. A first input coil and a first output coil extend around portions of the first magnetic path, while a second input coil and a second output coil extend around portions of the second magnetic path. The input coils are alternatively pulsed to provide induced current pulses in the output coils. Driving electrical current through each of the input coils reduces a level of flux from the permanent magnet within the magnet path around which the input coil extends. In an alternative embodiment of an electromagnetic generator, the magnetic core includes annular spaced-apart plates, with posts and permanent magnets extending in an alternating fashion between the plates. An output coil extends around each of these posts. Input coils extending around portions of the plates are pulsed to cause the induction of current within the output coils.

Specification

This application is a continuation of copending US application Ser. No. 09/656,313, filed 6 September 2000, titled Motionless Electromagnetic Generator. Its specification — the background, the summary of the invention, the description of the drawings and the detailed description, including the bench measurements at eight input voltages from 10 to 75 volts at 87.5 kilohertz and the extrapolation to 100 volts in — is the same text as the granted patent, and is carried on this site at /library/stm-925ae07652 rather than repeated here.

The way in

https://patents.google.com/patent/US20040057255A1/enA United States published patent application is a public record and its text is public domain, so it is carried verbatim here, exactly as the site carries the granted patent it continues. The claims below are reproduced in full because they are what distinguishes this document: the application is a continuation of application 09/656,313, which issued as US 6,362,718 B1, and its specification is the same specification word for word. That text is already on this site at /library/stm-925ae07652 and is not duplicated here — a second copy would teach nothing and would make the library look larger than it is.
