Permanent magnet assisted motor coil designs

Here are two scope shots. The only change was 1 shot is using a 10k resistor on the mosfet gates, and the other uses a 1k resistor. Could this be showing up due to the spec difference between the P and the N mosfet?

Your CH1 is set to 2 V/DIV it seems and your scope probe is across the two series coils, right?   
Would like to ask what was your supply voltage feeding the setup when you took the scope shots?   

Please also tell whether you have any load for the captured flyback?   

For the p and n channel MOSFET switch to work properly in this simple circuit, the supply voltage for their gate circuit should be way higher than the sum of their individual gate-source threshold voltages to be able to switch both on correctly.  Threshold voltage is around 4.5 Volt fet type dependent so at least a minimum of 10 Volt supply voltage should be fed across the two resistors the reed switch activates.   
The erratic switching at the "wrong place" may indeed come from the threshold voltage differences, how this is connected with the lower value gate-source resistances is not clear yet, (resistor tolerances and voltage division) if the supply voltage is too low, they cannot switch properly due to the poor DC bias, this may be one reason.   
You can always separate the drain voltage supply to the MOSFETs from the resistors supply so that the latter would get say at least 10-11 volts while the MOSFETS with the coils could get a lower voltage supply if you wish to avoid higher spikes developing now. 
EDIT It is possible the scope settings did not consider the 10x probe and 20 V/DIV is involved?  So you have about 12 V supply voltage...

It's all done from the power supply set at 16v. I have been having issues getting the scope set correctly. It seems the autoset feature keeps showing wrong for the v. I have something set wrong. But the wave is correct. I needed to unplug the scope and let it set again. But it is 16v supply. I'm still learning the scope settings.

I think you would need to choose manually in the Menu of CH1  the x1 or x10 etc multipliers when your probe is set to x10 and not 1:1.  The correct amplitude settings can be checked by measuring the square wave test amplitude with the probe and see the displayed amplitude and compare it to the one written under the test pin output on the front of the scope. (maybe it is 5V_pp)

When you have the 1 kOhm resistors in the circuit, hook up one probe GND clip to supply negative and the probe tip to the gate pin of the p channel MOSFET.  And hook up the other probe tip to the gate of the n channel MOSFET to see the switching waveforms.  The 16V should fall to around 8V on the gate of the p channel at the switch on moment of the reed and the zero voltage on the gate of the n channel MOSFETR should jump up to around the same 8V level when the reed is on. 
Is it possible the reed switch is abused from earlier setups? If so the 8 mA current (16V / 2 kOhm) may make the internal contacts uncertain versus the 0.8 mA current (16V / 20 kOhm).  _This may not be a case but if you can replace this reed by another one, you will see.

Thanks again for all the help from you guys as I learn moving forward!


Oh, there is no doubt in my mind the reed switches have been abused. I'm waiting on some more. I have had to thump them a few times already after realizing my circuits weren't working right. They are working properly in general enough to run with them since im out of replacements and my other glass ones were junk from the factory. But at a micro level such as that, I need to replace them all. I've kicked their butts accidentally during my learning curve.  I will revisit this subject after I get more and swap them out. I did get my P channel mosfets and my spring scales. After a quick throw together, I got all 3 coil pairs firing as they should. There is a nasty rats nest of wires so I will hopefully solder up my driver circuit tonight and start preparing for an efficiency test after a little more tweaking. I would like to know if I am actually seeing some benefits from these coils or if i need to make some design changes again. Maybe I'll at least know if it is moving in the right direction. I would like to know if I've built a 25% efficient motor or if it's actually showing promise.


I need to shoot a quick video of some findings I had testing out my recovery circuit while I waited on parts. But I've got to clean up the rats nest of wires I have everywhere first so you can at least tell what is being filmed. I've got a few ideas for helping with Lenz on the generator side I can't wait to test. But 1 step at a time picking apart each phase so I can learn as much as possible!
