The ever elusive magnetic motor

[The Ronin]

Great to see the improvements on your device, Bill. I was quite impressed with the torque before, but now it's even better. No doubt this can be further improved if needed at a later date.

I have seen other magnet motors which have got a few a revolutions before but none that have managed to pass the magnetic gate as many times as you have managed with one 'push'.

I remember the guy at magnetnerd.com made something like this but is a firm believer that it just can't be done. I did laugh to myself about the comment of using a "drinking bird" to move the stator.

I have no doubt that with your no-nonsense approach you will be able to harness the energy to reintroduce the stator to the turning rotor. Whether or not it will produce the desired effect, or can continue to do this is another matter altogether.

Its certainly a work in progress, I am curious would you please let me know what devices you have seen that gets through the gate on even the first revolution using only permanent magnets and starting from a static position.
As always thank you for your input!

Bill;

While I am very impressed with what you have accomplished so far,
you are also espousing beliefs that seem off the mark. Meanwhile, I
want to thank you demonstrating features that allow me to see what
is going on here, and I hope you continue with your attempt. I suggest
that you review the following carefully before you *give up* on this
project, however, even if it means altering your approach.

I have a design for a pendulum device, presented below, that I think
takes into account balance of energy issues somewhat more
sensitively than your motor;

---

The Basic mechanism:

A) The pendulum would have the Mylow style rotor magnetic array
mounted on a crescent shaped drive board at its tip. A pendulum is a
better device for this application than a motor rotor because 1)
it's "back and forth form" matches the motion of the "back and forth
form" of the movement of the stator field magnet. Rather then a clutch
for rotary motion. 2) If your magnetic drive array is circular and has a
unitary sticky spot the pendulum does not need to transition the sticky
spot with its field magnet turned on!. It simply uses gravitationally
stored energy to back out of it's own position, back to the beginning.
3) A pendulum is fully self instrumenting since the energy is continually
interchanged between dynamic motion and gravitational stored energy
and is indicated by the limit of the rotor motion. A pendulum almost
begs to be modified and optimized for stored energy.

B) A cable drive mechanism; a dual windlass drum would be attached
to pendulum axle at the fulcrum.

C) The stator magnet is attached to a disk (rather than a hammer) in
a way as to minimize rotational momentum. Minimizing the rotational
momentum of field drive board is essential because all rotational energy
is dissipated when this drive board hits its stops. It is not necessary to
have this stator field magnet move particularly rapidly.

D) The above should be gotten to work rotating the field magnet board
by 180 degrees as the pendulum  is rotated by 100->120 degrees, or
so. Later the stator magnet board would be reduced to 90 degrees
with stops when the storage mechanism (below) is made available,

Escapement Mechanism of the field magnet;

E) The key to making the motor/pendulum work is the field magnet
needs to be operated based on an "escapement mechanism". This
guarantees that the field magnet does not change position until all
or most of the rotor drive array magnets have passed it.

F) one could use two metal pull pins for field stator movement
synchronization.

G) the energy for synchronization pin pulling would be brought in
externally, initially, but this energy would ultimately need to be
supplied from the pendulum itself after the device has become
operational. The pulling pins must not add any energy to the
pendulum.

---

Energy balance adjustments:

H) Convert the windlass drum above to dual drive cones (could be
lucite plastic or wood) so that the position of the cable intersecting
the drum can be adjusted. This would minimize the drive energy pick-
off torque required to activate the field magnet. This is manual
adjustment number one.

I) Add two hanging weights that absorb energy by changing of their
relative heights while the escapement mechanism is locked. Manually
adjust the size of the weights to the minimum required to operate the
field magnet. This minimizes the amount of energy being removed from
the pendulum during operation. This is manual adjustment number two.

---

Magnetic drive;

J) Adjust the magnetic drive by making it as powerful as possible. One
way this could be done is:

http://www.overunity.com/index.php?topic=7770.0

Note that one still wants to have a unified sticky spot. The field drive
magnet needs to be able to be inserted in line with the magnetic array
smoothly.

K) Note that user Ergo is wrong about the magnetic drive. At the very
least, one can sort the magnets from weakest to strongest, to where
they pull each other through to the field magnet in turn, to spread the
energy being generated over the entire rotor array. This will make the
the sticky spot stronger and rotor drive unidirectional, but so what?

---

The sole determinant of whether this will work or not is; Is the excess
energy above what it takes to lift the rotor gravitationally, is that
greater than the field rotational momentum energy of the stator field
magnet? Friction in the mechanism is factorable therefore is not as
important.

In your motor design I'm concerned that the strong puck magnet is
being pushed out the way laterally by the hammer when it drops - this
initial acceleration will need to paid back during the disk rotation as the
field hammer is reset and doesn't necessarily represent gained energy.

So, how are you doing with this device?
Any progress to report? Good or bad news is welcome!
I'd love to see a real overunity magnet motor in action!
