Welcome to our forum for all things "alternative energy". You
are very polite. I am quite busy, but I always have time to
tell you what I have tried that didn't work, or maybe things I
would try if I had the time.
I looked at the link you provided and that is exactly what I am
seeing. I was also trying to have the coils generate back to
the battery part of the cycle. I don't believe this will be a
self runner, but it is different from a typical DC brushed motor
or PM brushless motor.
A couple thoughts about the Lynx Joule Motor:
1. The two coils should be together to get the induction from
one to the other. No ferrite should be used to prevent eddy
currents and cogging.
2. The flyback spike with the current design isn't enough to do
much. Might be high voltage, but not much amperage. A lot of
thought should be given to when the coils are generating. There
is only one position where one of the coils is powering the
motor.
3. Unlike a Bedini, this motor runs fast and with more torque,
and draws more power as load increases. A Bedini motor runs
slower and draws less current when loaded and doesn't make a
good motor. It is a good battery desulphater.

admin.
thanks for your fast answer.
I mentioned politeness because English is not my native language
so I`m never sure if I write some mess ???
You stated in 1. The two coils should be together
Does it means that the coils in your motor are not bifilar as in
the link I sent?
Are the coils winded one over the other as a kind of primary and
secondary (transformer kind) ?
Cheers
Alvaro
Edit:
Ill like to know your thoughts Dean as I see you`re wise with
circuits

Your english is good. Where are you from?
Currently my motor has the two coils 90 degrees apart. They
could be together and it wouldn't make a difference in how the
motor is driven, but the collapsing field would induce a current
in the other. Not sure that would be a good idea unless the
secondary is reverse wound.
Fun to play with. Check out my first videos on this motor
(youtube Lynx Steam) and it is clear to see how the motor is
wound. The red wire (generator coil) is 30 awg and has 300
turns. The green (drive) is 26 awg and has 120 turns.

From Spain (living in Malaga now)
I saw those vids. the first one at the time you uploaded them.
but in the late versions, I cannot see how is the winding.
Anyway, IŽll try to replicate the main circuit as showed by
Dean, but I`ll try to wind some 6 or more coils Tesla bifilar
series pankake stacked and connected in paralel (see last
sycollection vids)
This will take some time (may be a week), soooo, will post here
when done
cheers

Hey! Let me know if you need any assistance with the circuit.

Hopefully this picture will help explain what I made and what I
think would be an improvement. Dean's circuit still works and
should work better.
The diagram at the top is what I originally have been trying.
The diagram at the bottom is with both coils wound together.
They should both generate in the same direction. Just the green
wire coil is the drive coil. And now we gain the BEMF pulse.
So the question is how to wire these coils to make a smooth,
efficient, cool running motor.
If you look at my first videos of the Joule motor you will see
the wood and common magnets for testing. Pretty simple to make
as a test platform. Is this a window motor?

I did a quick test with the coils wound together and criss
crossed at the back of the motor. Just powered the drive coil.
Very fast strong run. Checked the AC off the gen coil and it is
indeed very spikey, high voltage like a Bedini. Will test some
more and post results. Haven't fully hooked up Dean's
circuitry. Need some parts.

Admin - The diagram at the top is what I originally have been

Dean - What is your name - anyway???
The Drive BEMF pulse was never lost from before - it's discharge
path was through the secondary coil and the battery. The
reluctance from the secondary coil would have limited that
pulse, that's why I said 'I don't see allot of Back EMF'
To answer the question - you wire each coil the same way you did
before, pick a direction and find out which way the motor spins
when you apply temporary power - if it spins the wrong way,
switch the wires around. When you find out which wire goes to
positive, mark it and then connect it positive to negative (coil
to coil). That will keep the phase correct.
(Future Test) To keep it cool? - try a old computer fan on the
shaft - that will put a load on the motor and give the torque
something to push against. I'd like to see what kind of voltage
drop you get in that situation.

Dean,
My name is Marcus and I will use this handle "Lynx Wind". Using
the name "Admin" was sort of too serious.
I spent time messing with the original Joule Motors. Rewound
both. It turns out that each coil is bifilar with 26 awg and 30
awg, wound the same direction. They can be wired in series
start, end, start, end. The start wires for both primary and
secondary go to collector. The end wires for both coils go to
positive rail with a diode between as you have shown. I used an
LED between the two coils and it is interesting to watch the LED
get bright as the motor runs.
I put a load on it and it has good torque. The motor is much
smoother now and rpm higher.
Speed can be adjusted with duty cycle. Because I am using a
magnetic reed that pulls in or pushes away I can adjust the duty
cycle by adjusting the pressure on the reed. If I set the motor
to run at 1 amp and put a load on it, speed drops but amps
remain the same. Voltage while running drops but very slowly.
If I run the motor without the circuitry, and just run DC
through the reed the motor runs hard, the coils get warm and the
amp draw is 2-3 amps.
I will video the motor running with a load this evening and
post. I think this motor is worthwhile to explore. It
definitely drops voltage very slowly compared to a typical
brushed DC motor.

Hi:
I have been experimenting with a DC motor with bifilar coils
(posted on youtube by Tom Ferko) and wonder if the system could
be made to power itself using the regenerated energy. Could you
post the latest schematics for your motor as I understand you've
since improved the one shown in your video. I'd like to see how
it compares to the one shown on totallyamped website. and if it
could be improved. Thanks a lot.
