Strange power generation system

A
basic replication of this device, as well as several video clips,
can be seen at:

http://nuscam.com/testing_now.htm

A young grade-school girl built one too.

http://www.keelynet.com/bedmot/bedmot.htm

Think of this device as an "energy gatherer". This is not
perpetual motion, any more than a windmill being pushed by the wind
is perpetual motion. It's just using certain ambient energy sources
by concentrating and releasing them.

For the full theory of operation, read the following page and the
links at the bottom of that same page.

Enjoy!

Here's
a picture of a working model. Instead of using a belt for the
timing, this one uses two magnetic gears made up of many small
magnets around the outside edge. The two "gears" don't actually
touch. The fields lock together like teeth.

The larger wheel turns at about 2 rps and discharges the output
capacitor with each rotation.

The main rotor is running at about 2000rpm.

This motor is running on about 150ma input at 12v. Every input
pulse is bounced back out to the collector capacitor and sent to a
second battery to recharge it. The more you load up the axle, the
lower the average input current drops.

It is based on the model design found at:

From
the video it appears that alot of energy is first applied to the
fly wheel, then the power used by the bulb slowly slows down the
flywheel till all the kenetic energy is consumed by the bulb.
Fun to learn about basic physics though.

Oops. I hit the post button before I finished my reply.

The stator core is made from individually enameled
strands of soft steel wire packed tightly and epoxied in place.
It's an extremely efficient three-winding 1:1:1 transformer with
very low hysteresis and eddie-current losses.

As a PM approaches the core, it generates a positive voltage
and current on the base of the transistor, turning it on.

The transistor switches fully on and applies the battery to
the primary winding to oppose the PM field. This happens at TDC
where the PM field is compressed just enough for the rotor to
"glide" past TDC as if there were no stator present.

The transistor just as suddenly switched off, collapsing the
current-generated field in the stator. At the same time, the PM
field expands at nearly the speed of light and tries to "reach
out" to grab the stator core once again.

THIS is where a CAPACITIVE LOAD is applied to the third
winding to collect cemf. According to LENZ LAW, the now INCOMING
PM FIELD produces a massive power spike and as current is drawn
from the winding, an OPPOSING FIELD PUSHES back at the PM field,
accelerating the PM AWAY from the stator. The heavier the load
of the CEMF the greater the torque on the rotor. Yep, sounds
insane on the face of it. But, it works.

This explains the basics of Lenz law.

http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html

Notice that the law only applies to "fields" not to the
"physical structure" that contains the fields. In other words,
the physical magnet is a separate entity from it's field.
Otherwise, you'd never be able to distort the shape of a PM
field in relation to the PM's shape.

In a nutshell, the SHAFT TORQUE is an entity INDEPENDANT of
the user's power input and CEMF output collection activities.

This is called ELECTROMAGNETIC REGAUGING.

Actually, it's just solid MIG welding wire (hardware store).
The core is a piece of 1/2" ID CPVC pipe with a couple of PVC discs
glued on either end to make a plastic spool.

The strands of wire are cut slightly longer than the core and
then stuck in a foam block so they can be spray painted with epoxy
enamel. Once completely dry, they're packed into the spool and the
ends are cut flush. Then I use some glue in either end of the core
to fix them permanently in place.
This particular stator is a 500
turn tri-filar winding of #24 magnet wire. The wire size is not
super critical. But, that's a good starting gauge for a basic motor.

The TIP3055 transistor has specific characteristics that make it
useful for this application. Various bipolar transistors will work.
But, this one is cheap and plentiful. Mosfets will not work in that
circuit because they are voltage-controlled, not current-controlled.
Darlington transistors won't work either because they can't switch
fast enough.

In a nutshell, for this circuit, you need a relatively high gain,
fast switching bipolar
transistor.

While that method DOES allow you to build a transformer
with the proper turns-ratio, it gives you three windings with
varying impedance. You don't want that.

Make it a "tri-filar" winding. Use three spools of magnet wire.
Feed your coil form with all three simultaniously. This will leave
you with three windings with matching impedance.

ok ,
sorry I am not getting idea across , yes my question would have been
winding
all three at once  , so using three spools start
with  all three wires at the top , wind
to bottom , tape off
, return to top start next layer winding to bottom

or start with all three wires at the top , wind to bottom tape
off start next layer from bottom  ,

It
doesn't matter which end you start on or whether it's CW or CCW
winding. Just attach all three wire ends to the same spot on the
spool at one end and then start winding back and forth until I get
500 turns.

You should just try to keep the windings as neat and snug as
you can manage.

I
have a 8.5" x 2.5" al flywheel in the works , would it still
work if I put the magnets on the side face instead of the
outside face ( I am thinking it would)
it would be a lot
safer if I could , would not fly off as easy.

my magnets are 1" x 1/2" round N45 neo's

also would it miss up the effect if the frame was AL.

thanks

Almost any embodiment will work. If you're putting the
magnets around the outside of the rotor, use superglue to hold
them in place and then put a couple of wraps of fiberglass
packing tape around the outside. Using neodymium magnets,
you'll have a pretty decent gap between the stator core and
the PM's so the tape won't get in the way. I just used the
glue and left it at that. No problems after many weeks of
2000+rpms.

Uh oh, I feel a "too much info" moment coming on........

I'm going to quietly suggest that you build with wood or
plastic for the frame of the first motor. There are some
simple adjustments that you must make to get it running
properly.

Aluminum is ok as long as the PM fields don't end up
getting dragged through the stationary aluminum parts. That's
going to be an eddie-current area that will cause drag on the
flywheel. It won't specifically change the inductive effects
in the stator. But, it will detract from the available shaft
torque and make it run slower.

All the positive shaft torque is provided by only two
things.

The initial attraction of the incoming PM to the
stator core.

The CEMF loading (capacitor charging) as the PM
is moving away after TDC.

Your battery input is only
enough to cause a "null" field at TDC, not a "push" after TDC.
You will need to short your battery into the primary winding
and adjust the gap between the stator core and the rotor
magnet to see where the "null" zone is. Use an almost dead
battery (10.5v) to do this adjustment.

More interesting stuff....

The incoming attraction for EACH SINGLE
PM-STATOR INTERACTION is exactly the same amount of torque,
each time, regardless of the RPM. This means that the
available working force from the attraction increases in a
linear fashion with RPM's.

The input pulse from the battery and the CEMF
output pulse have a fixed efficiency relationship that is
determined by your stator design. The maximum efficiency for
battery recharging is by allowing the capacitor to only rise
a few volts above the receiving battery's voltage before
pulsing. This is why the motor has that simple timing wheel
arrangement. ALL MECHANICAL means that you can study things
very closely. Using a larger capacitance keeps the pulsing
voltage lower and allows greater standard charging
efficiency. Always make sure the input and output batteries
are the SAME VOLTAGE. The 1:1 transformer effect guarantees
that the charging is provided ONLY from collected CEMF and
NOT from primary pulse current. This will make more sense if
you place a lower voltage battery on the output and watch
what happens to the input current and shaft torque.

JUST BECAUSE you are extracting the CEMF with
the capacitor, the PM gets an extra "push" as it's leaving
the stator. This is because the PHYSICAL MAGNET is moving
away from the stator at the same time it's FIELD is trying
to APPROACH the stator. Lenz law applies and the load during
this phase causes a reflected field from the stator that
"bounces" the PM away even faster. This is much like
dropping your glasses and trying to catch them in mid-fall,
smacking them across the room like a tennis ball. oops.

thanks , I see a plexiglass rotor and chassis , and
problably only one magnet , but that is just a guess , also from
looking at the patents I believe they are using a electronic timer
to dump the cap i.e. count 3 pulses , dump  ,etc

I guess I have to build one , while I am waiting for my AL
rotor to be finished

Very astute observations. Except that the flywheel
probably has 3 magnets spaced
120degrees apart near the edge,
to maintain balance.

Notice that the "motor" aspect of the device is not used for
anything except timing and "firing" the inductors. The rotor
magnets must be spaced properly so that they pass the stator
fast enough to generate the trigger voltage for the transistor
base. But, at the same time, there must be enough time between
interactions that the next magnet doesn't overlap any of the
electrical action of the previous magnet. Make sense?

The "motor" is an electro-mechanical PWM that set's it's own
frequency. Very little interaction between the rotor and stator
is required when a very high-gain transistor is used. This CAN
be done with fancy solid-state controls. But, a mechanical
system is easier to maintain since it keeps your solid-state
parts count very low and very simple to work on.

As the webpage describes, the transformer effect uses only
the CEMF or "radiant" aspect (ala Tesla) which is pure
potential, with no electron current. Until that radiant spike
"lands" in a capacitor, it is not "real" power in the truest
sense. Funny thing is that you can put the capacitor at the
other end of a few thousand feet of wire, and it will fill at
the same rate. Freaky stuff to see when you've already been
trained to think in standard textbook theory. I've been beating
my head against this stuff for several years now and one day,
not too long ago, it all finally began to click.

I hope I can help accelerate the learning curve on this for
some others.

well ,
I first try at this motor has not worked, this one I made the rotor
out the plastic that they use for cuting boards , 1 inch thick ,
plexiglass frame / 3/16 steel slaft and bearing

used 1/2 x 1/8 round neo mags ( maybe I should use ferrite like
bedini said ?)

coil 1/2 cpvc pipe and 1-1/2 spool ends , #24 motor and gen wire
#26 tigger , wound until could not put any more on coil form all
wires at once .

used .030 soild mig wire to fill core , spray painted each wire.

2n3055 trans , in914 diode , 330 resistor , 1000v bridge and 330
uf 500v cap

no dump yet , just wanted to get the motor to run

lined up coil to mags , I am able to adjust the gap by moving the
rotor up or down

coil does repeal , adjust to null zone as per directions , spin
rotor and it stops

using 12v battery scope shows waveform on all windings

sometimes the circuit will start to oscillate without the rotor
turning and when one of the mags is tdc, when this happens I get up
to 150 volts on cap and trans gets hot

any ideas , what kind of mags are you using ?

I have the tigger wire like the

Make sure you're using a TIP3055, NOT a 2N3055. The
gain on the latter will usually prevent it from working
properly.

Go to radio shack and pick up a 10k, 15 turn
potentiometer. The part number is 271-343. Get rid of that 330
ohm resistor and put a 100ohm resistor in it's place. Then put
the potentiometer in series with it. Now you can adjust the
input pulse-width. Start with the lowest resistance setting and
give the motor a spin. Make sure the transistor isn't heating
up. Watch the waveform on the scope. You'll see the positive
sine, then the transistor "on" pulse, and then an hv spike.
Increase the resistance slowly and watch the transistor "on"
pulse duration. It should be decreasing. Keep turning up the
resistance until you see a second "ghost" oscillation. Stop
there and go back down just a hair to make it go away. If you go
further out, you'll get wild oscillating and the motor will
stall.

Yes, you SHOULD be using HIGH POWER CERAMICS, not
neos. But, you've already got the stator gap adjusted, so it
should work.

Disconnect the bridge and capacitor for now. It will
interfere with the motor if you are not DUMPING the cap
steadily. Without it hooked up, the radiant spikes will not
interfere with the motor action.

Lastly, You MIGHT have TOO MUCH INDUCTANCE in the
windings. This will lower the resonant frequency of the stator
and can prevent the motor from running. Since this is the most
annoying thing to fix, check all the other possibilities first.
If this is the only option left, rewind the stator and stop at
about 400 turns. Then try running it again.

Ohms don't matter much when it comes to the way this
thing works. This might sound weird. But, it's true. You've
already adjusted the stator gap, so you KNOW that the magnets
are attracted and then "zeroed" with full battery voltage in
the winding. Getting "motor" action is now just a matter of
proper components and tuning.

I've made all sorts of rotors out of MDF board, plywood
(yek, wobbled too much), bicycle wheels, pvc tubing "stalks",
etc....

What matters is the switching speed of the circuit, in
relation to the magnet interactions.

Once you've dabbled with these a bit, you'll begin to get a
feel for what's required.

Look at the specs for the TIP3055. As long as you use a
good bipolar transistor that meets or exceeds the
voltage/frequency/gain specs, it will work. Don't bother
trying any darlington transistors. They REALLY stink for this.
Too slow. You will get a nice THUMP noise each time you try to
start the motor, though. heh.
