Hi All,
This is my design of a magnet/generator design.
How it works:
There is a center shaft that is stationary that has a North and South magnet attached to the shaft. The field winding rotates on the outside like the Joe Newman motor.
This also has two magnets outside of the rotating field winding to increase magnet flux field on N/S. At 90deg there are two more magnets stationary to generate power output.
There are no iron core to increase flux to generate power, this would cause cogging effects. This will allow low power input to by theory increase output at 90deg.
The BEMF is collected as the field turn off after energized to cause rotation. A encoder and microcontroller would be need to control the timing and charging circuit.

Hi All,
I never like a theory, it's like telling someone a story without facts.
This is my intro video to make a theory into fact, even if it doesn't work I would have real data instead of a theory.

Hi All,
I'm explaining how this pulse magnet motor/generator works.
As you all may know, I don't like theories, that's why I'm building it to verify with some real data.
I would like to have some input form anyone, being open source is something I truly believe.

Such a joy having you back in the saddle Tom. 8)
Those window motors really have lots of neat characteristics, probably why Bedini moved in that direction as well as Newman and others.
Hi All,
I did a test run on the pulse motor, very slow to start.
The magnetic field saturation theory is correct. Where you can add magnets in the center and outside of the rotating electric field.
This was a good test, I hope you enjoy this project.

This is a update on this build.
Some crazy high carbon brushes it seems. Guessing they were made for something really high voltage where they wanted to minimize arcing.
I imagine you've found some replacements by now.
Overall, I think you'll be having all kinds of fun with this new gizmo of yours soon. Neat setup.
Hi All,
I made some contacts to replace the brushes, also test run again.

Hi All,
New update in this fun build. As you have seen the pulse motor is making progress, now I wand to start on the secondary winding for the output of power. This will allow charging the battery and separate input and out put of the build.
This is the video to explain more about the new added field winding.

Hi All,
This is the first test run on self charging pulse motor.
Not only does it charge a battery, it charges the primary power the is running the pulse motor with 13.30v charge.

Hi All,
This is the specs on this pulse motor input vs output.
Coil 1 (generator) 5.6 ohms, 18 gauge
Coil 2 (motor/flyback effect) 16.3, 26 gauge
Running mode 52ma pulse.
Coil 1 (generator) output 18ma constant.
Coil 2 (flyback effect) 23ma constant.
Due to the pulse not being constant and much lower, I believe the total 41ma is more energy output then the 52ma pulsating running the system.
This could be why the motor voltage is raising while its running.
Tom
Hi All,
Let me be very clear, I'm not claiming OU, but I have more data that may have to be verify on this self charging motor.
I'm doing a input reading with a filter of 200 ohms and 100uf electrolyte capacitor with a constant load of 5ma. The total resistance of the drive coil is 14.4ohms in the system, this could be due to the brushes. the resistance direct to the stator is 16.3ohms. Running power input is between 2-0 ma.

You mean
not claiming?
You're so close either way, but I notice you have nothing harvesting anything from the shaft rotation. You think there is (20mA * 12V) 0.24 watts of power there to gain back? If so, then you have a garage demonstration of power extraction from permanent magnets.
Hi Dog-One
Yes, I'm not Claiming OU, but it's very close.
I'm setting up a 64000uf (0.06403137537393323F )capacitor bank. Will it run and how long?
Tom
Hi All,
This is the first test run using 64000uf capacitor as the battery bank.

Now that's some cool stuff right there.
I think this is an excellent example of using an inductor as not only a boost converter, but allowing it to do mechanical work at the same time. You've done a lot of pulse motor builds over the years, but this concept you are demonstrating now may be on to something that can be easily exploited to achieve an overall power gain. Keep the creative juices flowing. Looking forward to what you bump into next.
Hi Dog-One,
Thank you for the complement, I believe we all can work together and try new things.

Suggestions...
Make all portions of your code that are time critical to be interrupt driven.
Languages...
I have had good success using CircuitPython (https://circuitpython.org/), especially on my Teensy 4.0 (https://www.pjrc.com/store/teensy40.html).
Be sure to include the asyncio library (https://learn.adafruit.com/cooperative-multitasking-in-circuitpython-with-asyncio) so you can process menu commands
and do stats or other housekeeping operations without impacting the main
signal processing. This gives you a pseudo-RTOS and once you build yourself
a framework that makes sense to you and works, you'll use it as a template
for everything else you do.
Like anything else, there is a bit of a learning curve, but once you get the
hang of it, it's a new tool you have in your toolbox for later use.
For the project itself, I think with the sensors you have and the design you're
striving for, it looks good to me. Should be able to run the guts out of that
window motor and collect all sorts of data to find an angle where you can
maximize the effect you're after.
Hi All,
Thanks Dog-One for your input.

Yeap, yeap, yeap, there you go...
Push-pull with a half-bridge? Yes you can. Just need a bipolar power source--two batteries.
"If" statements, also known as fuzzy logic. You can reduce much of this by coordinated
logic. For example:
Instead of:
if ((x && y && z) || (a && b)) { digitalWrite(A0, HIGH); }
Change things to:
digitalWrite(A0, ((x && y && z) || (a && b)));
A novice programmer will have a more difficult time reading the second expression
I fully get that, but the idea is to let the power of logic do the work for you. Once
you begin to think in logical operations, your code can be transformed directly to
pure hardware if ever need be. When I first started writing VHDL and later Verilog,
it took me quite a while to change my thinking and one day after many days fussing
with my code, the light came on for me. I never looked back. Now I can sit down
and draw up a state machine, map it directly to logic components and have it work
flawlessly. And the beauty in all this is, with logic you can't drive an Arduino pin
both high and low at the same time--one expression defines exactly what that
pin needs to do. You can execute that expression as often as you need to and
it will always do the right thing defined by your logic. Should you get in a situation
where you simply cannot process the logic changes fast enough, grab some actual
logic gate chips and wire them up the same way. It will run as fast as the chips can
go, usually in the MHz range.
Hi Dog-One,
Thanks for the information, that should help a lot.
Programming with a few different languages does get n the way. But over all, I know what type of program I'm looking for.
At first I got stuck, I was writing the introduction of the program, when in fact I need to have the motor running first and then modified the input/output controls later.
To have so many variables will slow it down, but I plan to read and write direct into the PIN registers. This will increase the speed even more.
Thanks again with your knowledge on the Arduino, it will save me a lot of time over all.

New update on the pulse motor.
Nice work Tom! Looking pretty good.
On the hall sensor, I'm guessing you have the Arduino looking at the signal
trailing edge instead of leading edge due to the polarity coming out of the
comparators. At least that's what it looks like from my angle. If that's the
case, I can see why the length of the magnet is determining your timing.
I had a crazy idea about collecting back EMF when the coil is triggered
bipolar. You did a lot of work in this area, so are probably two steps
ahead of me, but I'll try to describe it so others can chime-in if they want
to.
Suppose you connect a full-wave bridge rectifier to your coil and then
take that output to a cap bank. When the caps are empty initially, they
will suck a lot of juice from the coil that is trying to actually run the
motor. I got that much and would expect that behavior. But what happens
when the cap bank gets charged up to the voltage level you are powering
the motor at? Seems to me like the motor would no longer even notice the
cap bank anymore, like it's not even connected. But the cap bank would
still collect back EMF, but what you have to do different is not allow the
cap bank to get discharged below the voltage you're powering the motor
with. Let me toss some numbers out as an example:
Let's say the motor is being driven with 12 volts. The cap bank starts
at 0 volts. We switch on and the motor lugs until the cap bank gets
to 12 volts. From there the motor starts to run normally and the cap
bank juices up to say 24 volts. Let's keep the ground for the cap bank
completely separate from the ground of the motor supply. And let's
bring in another 12 volt power supply (or battery) and connect its
ground to the cap bank ground. Now between the separate power
supply positive and the cap bank positive we can attach a dump
load. Because of that separate power source, it's impossible to drop
the voltage on the cap bank below 12 volts. If we leave the dump
load and separate power supply connected, by way of the dump load
the cap bank will charge up to 12 volts and we can start the motor
without it even lugging initially.
Efficiency-wise this may be a bad implementation, but the concept is:
we can collect back EMF from a bipolar fed coil, we just have to be
careful not to dump the storage of it below the voltage driving the coil.
I have a hunch since the cap bank voltage will be higher than the separate
battery, it will actually end up charging the separate battery every
time we dump it. That could be a good thing, since we can power
a load and charge a battery at the same time. We just have to pay
initially to energize the coil. Maybe with some kind of battery swap
relay system this thing could run for quite a long time.
Anyway, just a crazy thought I had. Maybe you can make something
of it.
Hi Dog-One,
Yes, that seems like a great experiment, But wouldn't the cap stay around 12v if it dumps that into another 12v battery?
Lets say the cap got up to 14v and the battery is at 12v you are trying to charge, wouldn't that also mean that 2volts is only need to recharge the cap back to 14v?

You got it. So what's the best way to power a load and charge a battery?
I'd say let the cap climb to double the battery voltage and dump it. If the
back EMF is coming in fast enough, dump often. Use the dump voltage and
dump speed as a power regulator. If the battery is charging too much, dump
to a different battery.
It's kind of different approach to the Tesla Switch device, here instead of
a fixed DC, we use back EMF like a boost converter.
Yes, I see.
In fact the 2-way flyback circuit would work great.
