STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

Would you mind explaining the circuit you mentioned that could harvest flyback current?

Here's the link,

His images are self explanatory, as it shows the path of current during the steps.

Staffman,

I've been doing equations for the past three days to try to show output. I'm having trouble with the output coil equations. I know standard coil equations. But how can I calculate the amps in the output coil if the toroid is saturating and un-saturating, in say 1/1000th of a second. If the magnetic field (0.46T) generated by a coil (in response to the external magnet) around a 2000u permeable material is created by 0.02 amps of current, is that saying multiply the amps times the frequency(1000 times per sec) to get amps in one second?

It would be very difficult to calculate anyway since you can't know the field actually flowing through the core from the permanent magnets.
You could calculate the required energy to saturate the toroid coil's core if you know the core material and the ratio of on time to off time (50%), but the output coil current flowing during the off time, is a function of the field flowing through the cores from the permanent magnets which is actually unknown since not all the field would flow through the cores.
The interesting part, is this area can be improved by better design, so at what point does it reach OU if ever?

@k4zep:  I think you're right about the balance being of the utmost importance in this system.

@lumen:  Excellent concept to possibly manifest a working toroid meg generator into existence.  This is interesting and I'll have to take a good look at it.

@broli:  Thanks for your circuit and the simulations on the permeability and the information you posted.

@esaruoho:  Nice high quality videos.


This is great stuff!

Hi GB.

Getting close on my proof of concept motor.  With Honney doooos, running around on Xmas Eve, time is short.  Right now, only have two pairs of magnets N/S orientation top to bottom.  Quad-filiar coil is 180T, each coil on Red form is 560 uH, when in QF mode, only have 12uH total all 4 coils @ 12.5 ohms total on coil.  Core is crap.  Interesting enough, in generator mode only about 1 mv pp, excellent balance.  Could trim coils so totally balance inductance but not till I get one to run. 

Using a A1101 Hall effect into a 2N7000 driver to a IRF1405 output.  Perfect square wave to coil.  with only 12uh measurable inductance, will Still shock the crap out of you if across the coil, have to shunt with diode across coil to keep under contro..  Extended run with it but not quiet running yet.  Even @ 18VDC pulses, core is not saturating....arrggghhhhh.  Anyway, having fun.  Sure wish I had 4 GOOD low u forms! 

To all the folk who want to know how to collect back EMF/kickback...go to Bedini School Girl Forum, Build one of their simple pulse motors, worth a thousand words.   I simply do not have the time to teach right now. 

Picture below.
Ho Ho Ho to all.

In this recent video of the demo you can see during 15-20 sec mark, a very clear animation of the device. You can see that there are total 16 magnets and 8 coils. If you enable HD mode you may even see the wiring.

Its my guess that only one magnet and one coil should be enough to check if its OU. You don't even need to collect the BEMF back into the power source (cap or battery or anything). Simply assume that you have 90% of energy back every pulse, in your calculation. Thats the first and crudest step. All the best to all of you

BTW: In his later video TK has explained the working principle very nicely, read the video description on the right. Strangely he has changed his tune.

The low voltage generation is interesting. I think this is why they said almost 100% cancellation. In practice this is impossible as you need identical magnets and precise component positioning for 100% cancellation. But an advantage of orbo is that the induced emf can be either backwards or forwards to the applied current from battery. This might seem strange but there's some logic behind it. The same reason why EMF cancels in series hooked toroid with opposite windings.

Nice setup btw.
