Circuit setups for pulse motors

@ Artic quote......i just got some supplies and i will be making the magnetic rotor very soon! soo excited...........................

That's the best way to go Artic.  When you build your own working circuit, you can measure parameters as you are making changes to your circuits, and the results will not only answer most of your questions, but will be more fun acquiring, than just questions and answers alone.

@Casman  quote.......
Came in this morning and now find my readings are 25V (same as yesterday except it does now bounce down to 24.9V). What this proves to me is that all of us are fighting the battle of losses. We loose it in the transistor or Mosfet or any mechanical switching such as commutators.

Hoptoad, I'd be open to suggestions as to overcoming these losses. More pickups? different switching? Don't really know at this point but what I do know is that the marriage of Adams and Bedini works well. Yes I'm still using the collector diode with the relays and it still works just fine. Can't wait to get a little down time to wind my hollow cores.................................

Carl, if I knew how to overcome these losses, you'd already be buying motors and generators directly from me! 
The real 64 million dollar question is, can anyone overcome these losses?. Oh and by the way, you forgot about the loss due to resistance, of the coil itself!  Dang it !

If you've got an unlimited budget, you might wind your coils with palladium wire onto an amorphous ferrite core and have it super chilled in liquid nitrogen!  But that only takes care of coil losses    Theres still pesky little losses in the switches and diodes. Maybe they can be superchilled too ? Either way, the total solution is way out of my budget, and probably yours  too   

In the meantime :

Optical signal switching combined with Mosfet power drivers, offers the lowest signal loss with the greatest signal timing accuracy and variability.

Multiple drive coils will generally increase the relative efficiency of the motor. Multiple drive phases, will definitely increase the relative efficiency of the motor. That is, a three phase motor is generally more efficient than a single phase one.

High impedance coil systems, reduce relative system losses due to heat, but are not conducive to high mechanical torque production.
But you can get around this with a low impedance secondary winding, using ordinary transformer step down effect.

High speed / high frequency pulse motors are more affected by inductive reactance.
This can be a very good thing!!!!

who cares about losses? what we need to look at is getting the motor to run itself.  after maximizing the motor as much as we can, try having it power a generator, check the power in verses the power out by the generator and we will know if it can power itself and as such we will know of its effeciency!  one thing i like about these motors is if you buy an RC car motor it has caps to ground out electro magnetic interference with the radio on board, what about connecting a diod on that motor directly from negative to positive? most likely wont do any good in the real world because it uses a comutator or such but if it didnt and the coils remained connected. how much current would it draw? how much horsepower could it produce and inevitably how much electricity could it make?  i personally am looking to limit the draw as much as possible and keep the horse power. it would be nice however if i could also make a model with the sole purpose of keeping caps charged to power the other motor   and you know there are some really nice caps out there!

so its been difficult but i am waiting the final hours for the rotor to harden. i used resin to encapsulate my magnets. i had to cast a rotor first then drill the holes and put the magnets in with additional magnets on the rotor to keep them in place, (2lb neodium magnets) and now they are sitting in the second resin casting to keep them in place. once done i can rig up the mount for the motor us it to round the final shape of the rotor (need to make sure its balanced and as thin as possible) then im ready for the coils and curcuits! ohh the excitment! hopefully i can get a generator constructed from this rotor that will do some good work, idealy it will generate enough power to power a second motor configured to run a go kart. the first step in taking over the world! MUAHAHHAAHA ok so maybe this isnt dexters laboritory but hey this is some fun stuff! 

whats the most powerful magnets someone is using on this forum and how is it working for you?

Im using  n45 2 inch by 1 inch round neos in my experiments. however my adventures are now towards hydrogen production and the implementation into a Vehicle.

Honk,
Hope your HHO project is going well...
Changed up a few things here and finally see some positive progress.
1. Changed drive to relays. Two, switching two Adams style coils (bifilar) at different times.
2. 3A reed switches to adjust pulses on coils.
3. Center tap on coils (both) is feeding a 10K uf 60V cap which, by use of another 3A reed switch, is feeding back to the primary battery through a 5W 2ohm resistor. Have been using another coil (not Adams style) to charge a 47K uf cap which in turn gives the relays switching power.
4. Draw on input is +/- 250MA
5. Feed back to battery is pulsing over 500MA
6. All magnets (12) are north facing out.
7. Two small magnets @ 180 degrees on the inside close to hub are pulsing the reed to feed current back to battery. Started with a freshly charged battery which sat for a day and started at 12.95V
8. After 5 hours I am watching the digital oscope bounce between 12.97 and 12.93 staying in the 12.94 range on average.

Next step will be to add my third drive coil and take the center tap voltage off of it as well and further charge the cap.

One coil needs 24V to operate O.K. but with two alternately pulsed coils I can use a simple 12V
HR9-12 UPS battery. Very stable and has some torque.
Took the relays out of some old UPS units.
Timing is good, pulsed recharge is good, now to further refine before putting on bigger wheel. Current wheel is only 23".
Bottom line is this.., Very high efficiency with more power to capture.
