There is NO source code in the Zip file.

pulsing coils

Hi toranarod, thanks for sharing the functional diagram. So are you saying your pulsing the coils three times per magnet/coil pass interaction.
I rewired my coils, they are wired series/parallel with a total resistance of 4.6 ohms. It now repels the rotor easily at 36 volts, so 24 volts should work fine for just demagnetizing the coil/cores, as with 24 volts each coil will see around 12 volts. Will be firing it up later today.

YES I am. Three Pulses in the duration time of magnet in aliment with coil.
it give you a lot more control over the total operation of the motor.
Its something lot more people need to look into.
but it provides more back emf and less current draw.
I have tried up to 25 pulses per engagement. I will write it up as soon as i can explain the effects better because it changes a lot of parameters.

cheers Rod

Arrows
The red arrows indicate the direction of conventional current flow from the battery to the drive coils when the two MOSFETs switch on.
The blue arrows indicate the direction of current flow from the coils back to the battery when the two MOSFETs switch off, isolating the coils from the ignition cycle and creating a return path through the rectifying diodes back to the positive terminal of the battery.
The voltage indicated by the blue arrows in the picture below is the back EMF generated by the collapsing magnetic field within the coils. The voltage amplitude in this wave form can peak upwards of 300 volts but is only of short time duration. This is the energy that is consumed on the ignition cycle that is collected and returned back to its source supply.
The pink arrows indicate voltage being generated by the attraction of the magnetic field to the iron core. This is current induced into the system just prior to the switching of the MOSFETs and is of the same polarity as the EMF field. Consequently, the current returns to the battery creating a load situation in the circuit, producing an opposing magnetic field in the coils and reducing the drive RPM.
To make this system work to our advantage I am going to separate the induced current (indicated by the pink arrows) from the high voltage EMF (indicated by the blue arrows) allowing only the 300 volts to be returned to the supply and not allowing the induced load current to flow to the source battery.
I intend to collect the induced load current and utilize its potential in an alternative manner as it is unused free energy which should not be wasted, and I will discuss this in the future.

Hi folks, Hi toranarod, "virginer" umm, lol. Anyway, I built that circuit you posted, though I used what I had on hand for now just to test functionality. I did try using only NPN's, though it only powers a load halfway, i used an led for testing. high side isn't driven properly with NPN. So I used an NPN 2n3055 darlington for low side and PNP tip42 on high side with NPN 2222 as pre-drive and it works fine. Though I'll need a bigger PNP to run with the motor.
I haven't tweaked the motor wiring or anything yet, with the holidays and all. At least I've ironed out the circuitry for recharging a source battery.
Also, you said you're still getting some loading on your motor even with that circuit. That is surprising since the generated emf isn't supposed to exceed the input voltage, though we are dealing with a different kind of motor, so that may explain it. Time to get my motor running, at least with normal switching until I get the parts for the feedback circuitry.
So I take it when you said that, you plan on putting another transistor in the flyback leg or something.

Yes, that's what I mean, the source code.

Cheers, caru.

When you say hi level code . do you mean source code? The asm file?

Yes, that's what I mean, the source code.

Cheers, caru.

[toranarod]

Many thanks! Don't you also have a more high level version of the code?

in the Zip you will find two files, one of them is hi level code.

Hi folks, Hi toranarod, thanks for kind words about my setup, that is the air/core motor, I just modified it.
Thanks for showing that schematic, now that I look closer at things, I see the problem using the typical Bedini type single diode flyback capture method when running a repulsion motor and attempting to route this back to input source. When magnet approaches coil/core typical induced voltage generates a current and puts full load on the generator coils because the coils are shorted from the lower positive diode and that is why you put the other mosfet in there to prevent that short circuit.
I knew this, though I never looked closely at my circuits to realize it was a dead short and explains why all my tests in that regard slowed the motor to a crawl. I think bipolar NPN transistors can be used for both switching positions, though one circuit I built like that if I recall may have had heat issues, it's been awhile since playing with those circuits. The top switch may need to be PNP using an NPN stage to drive the top switch, similar to what you've shown using mosfets. I have to refresh my knowledge on that.

Radiant energy recovery circuit back to source Battery

Radiant energy recovery circuit back to source Battery
This is the solid state circuit to replace the relay circuit

The H switch MOSFETS isolate the coils from the battery to recover the back emf when the field collapses.

if you intend to build I will give component values.

Hi Rod,
where can we download the PIC program that you promised?
