Gravity Test Motor Might Work as Magnet Motor Platform
Replication variant of Tom Ferko's gravity motor with magnet assist
design turns out to not self-rotate. However, the dynamics of motion near
the fulcrum point provide interesting possibilities for a possible magnet motor
application.

ESCONDIDO, CALIFORNIA, USA -- In his professional life, mechanical engineer Ken
Hegemann specializes in designing and manufacturing what clinical studies have
shown to be the best toothbrush in the world. (Ref1
| 2) After
19 years of prototyping, the automatic HydraBrush
is now available in the market, and was recently featured in Popular
Mechanics. (Ref.)
It won the Frost & Sullivan 2005 Dental Product of the Year award. (Ref.)
On the side, Ken likes to tinker with free energy designs. He is
enthralled by the idea of harnessing the wheelwork of nature in new ways.
For around a year, I featured an image of his Bowman Magnetic Motor replication
on the home page of our corporate site. (Ref.)

This past Monday, he flew me out to see his latest creation -- a replication
of the Andy Gravity Motor with Magnet Assist, presented by Tom Ferko a couple of
weeks ago. (Ref.)
Tom said that he had a working prototype of the motor, but destroyed it in a fit
of paranoia.

I thought I was going to be seeing something that was working. I
apparently misunderstood his purposes for having me come view his device.
Considering his expertise, and the craftsmanship he puts into his work, it was
still worth the trip to be able to see what I saw and learn what I
learned. Besides, he paid for the trip, and he gave me three of his
automatic toothbrushes.
Ken Hegemann works out some math on an experiment we
ran on his motor.
In his replica, he increases the fulcrum ratio to 1 : 5.6, and instead of
using magnet cylinders on the inside of a metal drum, he used weights guided by
bearings in an off-set, circular cam track. He used expensive lineal slides with
ball bearings on the eight weight tracks, each costing about $125. The
motor has very little friction.
To verify that there was no gravity effect in play here, and that the balance
was a net zero, we ran an experiment in which he got the motor spinning at a set
rpm, using a tachometer, then would let it coast to a stop, while I timed the
deceleration. We repeated this three times for forward and backward motion
at 70 rpm and 100 rpm. The averages for forward and reverse motion were
statistically the same. For example, the average time it took to stop from 100
rpm was ~29 seconds.
Magnet Motor Application?
The thing that had Ken intrigued, and which caught my attention as well, was the
action of the weights as they came into the center of the cycle. The way
they twisted in relation to each other resembled a carnival ride. Ken
thought that maybe this action could be put to work in creating a magnet motor,
which harnesses not-yet-understood properties of magnetism to provide net motive
force. See video close-up
of near inside apex.

through the center of the fulcrum
Over lunch, we theorized about the possibilities. "If pure
magnetic power can be harnessed in a motor, then there are bound to be a
near-infinite number of ways that could be employed to do so, some more
efficient and cost-effective than others. This mechanism is likely to
provide one of those methods."
Back at his shop, he took a couple of washer-shaped neodymium magnets and
placed them onto two of the weights, opposite poles facing, and we watched their
action as they rotated through the center portion of the cycle. It was
easy to imagine an attraction followed by the magnets being brought out of
position to avoid the repulsion phase. Even in this little experiment, the
magnets pulling between the two weights caused the motor to advance, but the
proximity of the magnets then caused them to shift/slip on the weights.

movement on the weights.
I then taped some smaller magnets in place, but they were not strong enough
to pull the weights together, as the larger magnets had.
Ken and I also brainstormed what possibilities could be pursued if gear
mechanisms were added to change the angles of interaction of the weights as they
cycle through.
"When the weights are moving toward the 9 o'clock (closest approach) level,
they are coming together. During that phase, magnets could be positioned
to be attracting. Then past the 9 o'clock level, the weights begin to move
apart, during which phase, magnetic repulsion could be used to propel the
motor. A geared timing device could rotate the weights to cause the same
magnets that attract before the 9 o'clock position to repel after the 9 o'clock
position."
"I would love to see people to start working on this," Ken said.
"There are thousands of different ways to place magnets to test this
theory, to achieve a working magnet motor and then to optimize its
function." That is why he flew me out to see it.
One thing he would recommend doing different in the design, when employing
magnets, would be to have two parallel spokes radiating from the same axel, for
stability, rather than just one in the middle.
It may be that the result of using magnetic forces in these various mechanisms
may yield a net of zero usable force. However, Ken was excited enough
about the possibilities that he flew me out to California to see what he was
seeing.
