Hi T-1000,
Per your schematic, you need two Arduino control lines to control a single coil, or one control line per mostfet (or relay). For a 30 (or 36) coil stator, that would require 60 (or 72) control lines. The Arduino only has 54 digital outputs.


You should be able to simplify your schematic from Arduino to H-bridge since you will never turn on the upper and lower mosfet on one side of the coil at the same time.

Hi PmgR,

My personal appropach to whole thing is a bit different series connections with just half length driving which would end up with 6 wires per pole repeating 3 times in series in total. This will end up with 18 wires and 36 high+low pins in total to control.  I am also planning to test the simplified setup with all coils. Just in single line over E cores in series liike ШШШШШШ with driving coils going on the angle and similar to the concept picture attached before. Then will use all available space for output coils to see what output power I can get after simulating moving magnetic field.

Also if to apply 72 connections the middle logic part of circuit would need another addition for controlling 2 pins at once. Which can be simple set of low power pnp/npn transistors like in Piere's original video where he was controlling 72 relays.

Cheers!

have 5 of 9 relay boards working, everything wired and mounted.  (except signal/power to the last 4 relay boards).
Need to get a better current power supply. (supply for coils/caps).

Works just fine to set output to high, then set mode as output, no relays flicker or turn on...  and setting low to enable relay.

WOW d3x0r!... you are definitely a serious builder
Looking forward to your results
Thanks for sharing

   Some many post ago, one user here was going to run this up using armature switching. Was wondering if that user went anywhere with it? 
   I have been pondering this setup for some time now. As I can't seem to find a 36 vane core as I call it, I am unable to proceed with a build. That doesn't keep me from pondering the way he is getting 60hz from his setup. Has to be in the stepping of the program through the relays on and off. The program says to overlap as in turn the next one on before turning the last one off. That would create a spike in the power line circuit each time one was turned on and  again when one was turned off.  Since the program is running a serial mode operation,  there are many on and off modes creating spikes. The output will see these spikes as cycles.  But still not sure if there are enough spikes to create 60hz from. Then it is not a sinus wave at all either.

   I have laid out a design for a rotary switch system using brushes that do a make before break but all six sectors switch at the same time. Sore afraid this will screw up the output frequency for sure. I did a small experiment to see it lentz would have any effect on my manually turning a switching system and no it does not. One down for now. Just need that burned up motor housing to continue.
