US Patent # 6,362,718
Motionless Electromagnetic Generator
Patrick , et al.
(March 26, 2002)
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.

Description ~
1. Field of Invention ~
This invention relates to a magnetic generator used to produce
electrical power without moving parts, and, more particularly, to
such a device having a capability, when operating, of producing
electrical power without an external application of input power
through input coils.
2. Description of the Related Art ~
The patent literature describes a number of magnetic generators, each
of which includes a permanent magnet, two magnetic paths external to
the permanent magnet, each of which extends between the opposite
poles of the permanent magnet, switching means for causing magnetic
flux to flow alternately along each of the two magnetic paths, and
one or more output coils in which current is induced to flow by means
of changes in the magnetic field within the device. These devices
operate in accordance with an extension of Faraday's Law, indicating
that an electrical current is induced within a conductor within a
changing magnetic field, even if the source of the magnetic field is
stationary.
A method for switching magnetic flux to flow predominantly along
either of two magnetic paths between opposite poles of a permanent
magnet is described as a "flux transfer" principle by R. J. Radus in
Engineer's Digest, Jul. 23, 1963. This principle is used to exert a
powerful magnetic force at one end of both the north and south poles
and a very low force at the other end, without being used in the
construction of a magnetic generator. This effect can be caused
mechanically, by keeper movement, or electrically, by driving
electrical current through one or more control windings extending
around elongated versions of the pole pieces 14. Several devices
using this effect are described in U.S. Pat. Nos. 3,165,723,
3,228,013, and 3,316,514, which are incorporated herein by reference.
Another step toward the development of a magnetic generator is
described in U.S. Pat. No. 3,368,141, which is incorporated herein by
reference, as a device including a permanent magnet in combination
with a transformer having first and second windings about a core,
with two paths for magnetic flux leading from each pole of the
permanent magnet to either end of the core, so that, when an
alternating current induces magnetic flux direction changes in the
core, the magnetic flux from the permanent magnet is automatically
directed through the path which corresponds with the direction taken
by the magnetic flux through the core due to the current. In this
way, the magnetic flux is intensified. This device can be used to
improve the power factor of a typically inductively loaded
alternating current circuit.
Other patents describe magnetic generators in which electrical
current from one or more output coils is described as being made
available to drive a load, in the more conventional manner of a
generator. For example, U.S. Pat. No. 4,006,401, which is
incorporated herein by reference, describes an electromagnetic
generator including permanent magnet and a core member, in which the
magnetic flux flowing from the magnet in the core member is rapidly
alternated by switching to generate an alternating current in a
winding on the core member. The device includes a permanent magnet
and two separate magnetic flux circuit paths between the north and
south poles of the magnet. Each of the circuit paths includes two
switching means for alternately opening and closing the circuit
paths, generating an alternating current in a winding on the core
member. Each of the switching means includes a switching magnetic
circuit intersecting the circuit path, with the switching magnetic
circuit having a coil through which current is driven to induce
magnetic flux to saturate the circuit path extending to the permanent
magnet. Power to drive these coils is derived directly from the
output of a continuously applied alternating current source. What is
needed is an electromagnetic generator not requiring the application
of such a current source.
