Regenerative circuits.

[Web000x]

There are quite a few threads going on right now showing a regenerative acceleration effect, originally made popular by Thane C. Heins. This effect shows that you can bypass the "original" definition of Lenz law by speeding up the rotor. Strange things start to happen after the "threshold".

Once the threshold has been reached, drawing max power off of a generator coil will speed up the rotor. This separates action and reaction by a period of time since an inductor cannot charge faster than L/r. THEORY: This causes the next magnet on the rotor to be attracted due to the delayed reaction thus causing a torque additive effect to the prime movers shaft.

I fully believe that you can make an COP>1 from this effect. All you would need to do is add enough magnets, coils, or additional rotors on the same shaft so that the torque additive effect finally exceeds the wind-age of the system. You would then be able to remove the prime mover and watch the system run.

Here is a simple video that highlights key points of operation:

Very interesting I cant explain that one.

These are the motors I am talking about. If they had very low resistance coils and were run on a regenerative circuit their COP would be fantastic but the setup would be difficult because now you have to balance the power in the coils to the magnets as well.

I wish I had one

I wish i could make one. Since the Page above from Flynn is half dead. The contact us and the Home linkdont works anymore. I hate that, when it happens at Pages like this.
The Principle is simple, you have 2 Fields, what you stear with the 2 Coils into the 4th Bar. The Force at the Bar is then greater that you did need to close the Path. I thought about, how to control the Field with a 3 Arm Rotor or any other Sheets, that you can redirect the Field, but not really Luck on that, and, well, other Ideas come in between.
His Motor did run at 99% and he said, once someone will come and will connect a Generator on it, you still can make these Motors stronger by adding Magnets.
But now seems he dont ship anymore, for what Reason ever.

If you want to make a parallel path motor its not that difficult but this will have BEMF and you only pulse in one direction. It can be done with any universal motor but you have to use pulsed DC as the input.

You have to slot the stator like I have shown in this drawing http://www.energeticforum.com/attach...or-lockpp2.jpg
It is easier if you place the magnets on the outside of the stator then there is no interference with the rotor except where you want it.

The trick to making it work efficiently is to balance the power of the coils with the power of the magnets. That is, there is just enough power in the pulse to switch the flux path of the magnets. When you do this you get the power of the magnets plus the power of the coils rotating the rotor. The lower the power in the stator coils you have the higher the efficiency. you have to run the motor in attraction mode too. Obviously powerful magnets work better, but theoretically you could double the torque for a given input.

Because of the slots on the Lockridge device I am still not totally convinced that this wasn't using parallel path. I postulated this on this thread http://www.energeticforum.com/renewa...ath-motor.html. If you believe I could be correct post on that thread.

Hi mbrown,
i dont wanna say much about your Setup, i dont have any big Experiences with the parallel path. And so far i dont have one working i can not figure it really.
I have made the Bars and played around with it, but didnt find a lot on it.
But what i see at your Setup, is, i think the Gap at the Magnets will be needed, or the Flux will stay only around the Magnets, leaded through the Iron. Thats the other thing what i do need, certain Sheets, to got the right bridges for the Paths. And anyhow, there is no real Rotor at your Drawings.
At Flynns Motor it seems for me, that the most Force exist at the 2 closest Tooth from the Rotor, leading Flux through iron will weak it out very fast at a lenght, so i guess, you need to have a short Distance, where anything happens, means, the Flux from the Magnets come in with the Flux of the Coil, and still have a Space, where they enter or interact with the Rotor.

I haven't built this motor yet but I agree the position of the magnets in the drawing could be a problem as there will be an interaction with the rotor. The magnets would work just as well placed on the outside of the case. All my threads on this forum are based round the Lockridge technology and as that was made from 1930's technology, I think there was nothing really special about it.

I believe standard DC motors can be adapted to work this way but the problem is that nowadays too much resistance is built into motors for regenerative technology to take them above 100% efficiency. and the exceptions to that such as starter motors are made to be very inefficient so again the gains will be small.

I have been testing the regenerative circuits on coils and a couple of motors and while there is an improvement there is not enough. Making a starter motor parallel path as well might just give enough extra power to make it work but as I said they are not good motors. Making a standard motor parallel path relies on the rotor winding to create the appropriate flux path and I agree that this is not a perfect motor but I am trying to do it with 1930's technology. Modern motors have relatively low inductance too, this means we have to use high frequency switching to get sufficient recovery, too high to do it mechanically.

Generators may be built better and more efficient so it makes sense that Lockridge used a generator as a motor and they may be of higher inductance but I have not found one of those generators here yet.

One other point, series wound universal motors work best.
