Minato Magnet Wheel - 11/18/97
The information comes from Henry Curtis of Colorado.
He told me about an interesting machine he had seen while at the First International
New Energy Conferencea in Seoul, Korea (a group headed up by Mr. Chi San Park
held the first weekend of May, 1997). He noticed a spinning bicycle wheel
that was attached to a table. The wheel was running, yet there did not appear
to be any driving force such as a motor, belts, or gears. Henry said he watched
it for quite awhile and it never stopped running. On expressing curiosity
about the wheel, he was invited to stop the wheel. He then gave it a spin
with his hand and it began moving on its own. Henry swears it was the neatest
thing he'd ever seen. The following drawing shows the wheel arrangement, one
half was weighted, the other half had slanted magnets. The inventor, a japanese
man named Kohei Minato, has a U. S. patent (5,594,289) dated January 14, 1997.
It's similiar to the Adams
motor and uses 150 watts power input with sustained 450 watts output. The
counter weight is a single curved piece of aluminum covering 180 degrees.
Each of the several individual magnets on the other half of the wheel are
slightly asymmetric, crescent shaped and nested. They are magnetised end to
end with the N poles out. The motor is actuated by moving the N pole of a
large permanet magnet (the drive magnet) toward the wheel. As this magnet
is moved toward the wheel, the wheel starts to spin. As the magnet is moved
closer to the wheel it spins faster. The acceleration of the wheel is rapid.
So rapid in fact, as to be startling. The geometry of the magnets on the wheel
is very important and subtle.
Engineers are said to have measured an output/input
ratio of 4.3/1 and that the device can put out 500 watts with an input of 34
watts. As rpm's increase, the electromagnetic consumption of the stator decreases.
It operates without heat or noise. The stator coils have their pole faces toward
the perimeter of the permanent magnet wheel. Patent 5,594,289 states : "On a
rotor fixed to a rotating shaft, a bunch of permanent magnets are set along
half the wheel such that the same pole type faces outward. Weights are set on
the other half for balancing. Each of the permanent magnets is obliquely arranged
with respect to the radial direction of the rotor. The electromagnets of the
stator face the rotor and are intermittently energized.
