Request - A simple circuit to recycle flyback in a pulse motor.
« on: December 22, 2009, 12:22:47 PM »
Is there anyone here who could post a simple circuit that can collect/recycle flyback current in a pulse motor and put it back into the battery that's powering the pulse motor?

I would appreciate any help anyone can provide.

For example, lets say that a battery is connected to a wire which then goes to a reed switch which closes the circuit and powers an electromagnet and the wire goes back to the opposite terminal.

What is the simplest way to put the flyback current back into the battery?

@intrestedinou

I have been working on that for a long time and had have short successes but that is a very elusive spirit.

The back emf from the collapsing field? I think the Bedini SG or SSG basically does
this, as do certain implementations of the Robert Adams device.

I concur with both posters' previous topics.  The flyback idea is sound, but I don't think the power going in can flyback with as much force as it flies in unless precisely timed.

The Bedini device is supposed to use the momentum of a magnetic flywheel to re-send the pulse backward, as a magnetic field collapses, it does so in a direction reverse of the current put in.  As a pole of a magnet nears a solenoid, the ( a ) magnetic field is setup in such a way as to oppose this incoming field.  The two are supposed to work together.

They may in fact, and a flywheel would be a convenient way to create resonance which varies according to pulse characteristics, it will act like a pulse motor ( synchronous ).

Hi.

Here are two circuits, try to adopt to your needs, your pulse motor can be connected in the place of the coil, as THE inductance.

In the second link your motor can be connected to replace the RL resistor AND REMOVE diode D1 and place a short piece of wire to connect the circuit to battery negative. i.e. omit the D1 and short circuit its place.

The problem with pulse motors is that the coils if they have iron cores, change their inductance when the rotor passes them (approach, face then leave) so the collectable flyback pulse energy varies from 40-85% wrt the input energy. If the design of the motor is such that this inductance change is very little or there is not at all, then recovery may go above 90%.  (very rare)

rgds, Gyula

I am a laymen at electronics (but learning) and I am wondering if anyone here could explain a simple setup that could send the flyback current back into a battery. I appreciate the links, but if someone could provide me with a simple circuit I would appreciate it.

For example, lets imagine the following circuit. You have a battery and a wire comes from the positive terminal. That wire is connected to a reed switch and then a diode. The wire then goes to the electromagnet and back to the opposite terminal of the battery. The diode is setup so current can flow from positive to negative but not the opposite way around.

Is it possible to make another parallel branch of the circuit from a junction after the diode and just after the electromagnet? When the field of the electromagnet collapses would the current circulate around this circuit? Could I connect this branch of the circuit to the original battery and charge it?

`what you say, and what you intend to do, is use an inductor to ...

you want to charge a battery by discharging a battery.  You just want them to be one and the same.

It would be like getting a larger reflection than is input back instead of forth.  This is like the holy grail of electronic circuits.

I appreciate the links, but if someone could provide me with a simple circuit I would appreciate it.

The 2nd link provided is an excellent example to study.  It is explained in more detail a few posts further down that thread:
http://www.energeticforum.com/renewable-energy/4314-cop-17-heater-rosemary-ainslie.html#post56075
You would then:
RL = your coil
Q1 = your reed switch

(Gyula - thanks for that link!)

Also, 2 battery setups usually seems to be recommended: 1 for supply, 1 for capture as doing both on 1 battery causes stresses that lead to shortened life?
But in this case, the flyback/collapse is sent to the 'precharge' capacitor, rather than back to the battery so this is a cool modification!

Here's one that works quite well. The zener provides two things: impedance matching and enough of a time delay so you can feed your recovery pulse back to the power source.
These values are for my particular application so you would have to adapt the concept to fit your own device. A TVS diode is nothing more than a power zener, and they will handle a few watts of power. In my application I use an IGBT which is triggered by the zener to handle more power.
I suggest using the largest value TVS zener you can. 1 to 3 times (or more) the value of the source voltage in low voltage motors. Add the source voltage to the value of the zener to make sure you don't exceed the maximum voltage rating of your transistor.
The majority of the power savings comes from the impedance matching aspect of the zener and not from the little bit sent back to the front end. Try a few different values to see this property for yourself.

Cheers,

Ted

Flying off on a tangent, how much time delay?

I am thinking of another application uif electricity can be delayed for a very short while.

Check it out this video. And Watch all related videos(Pulse motor).

http://www.youtube.com/watch?v=LNoZ9DpUc4s&playnext_from=TL&videos=6h5yKaRsuGI

He make a high voltage to feed back to coil.
But I could not figure it out. How to hook up his set-up.
I asked the circuit diagram for the setup. But he reply me a message as below.

"Sorry i dont have time to draw a schematic right now but I can tell you that the circuit is quite simple and basic. I run the positive to the drive coil first . On the ground side of the coil I place a diode and feed it back to the positive side of coil. Then I turn the coil off and on with a relay on the ground side ,you must use capacitors connected to the relay points the radiant spikes are very powerful and will burn points , you must use large relay also or you will burn points. The relay is turned on by using a small pick up coil neer the passing magnets connected to a transistor which you connect to the small coil on the relay which pulls it in to turn it on.I also placed a 1k ohm pot on the ground side to the transistor to help control on time.Hope this helps you get started.
john U."

Anyone help me figure it out how to setup or hook up his pulse motor.
Thank you. :)

Seems like a diode is the best option for converting fly back to the coil.

Ted can one use that to a bedini motor. If yes can you show how to connect that circuit with the SSG bedini please?
Thanks
