Good job Sam!
Good job Sam!
When you powered both brush sets...you meant like parallel connect?...or with a rear jumper and top feed?
That's a lot of amps drop off
One question...are this two motors (Quad and G-10) same spec's as rotor wise?...If so, could you run the G-10 Rotor inside the Quad Stators/Brushes housing?
Mechanical drag, due to misalignment or rubbing parts is a killer for performance my friend...
That housing (on video) looks much better than the smaller magnets circumference/semi-rectangular type...you must realize that even powering just one brush set within four magnets you will get assisting on the reversing coils right after collapse...you do not have that option on the latest one.
The second draw back on this type (rectangular housing) is that you could not adjust brush timing...and all this motors need a "final tuning" after first run...I do it while running...and meters on...to check best point at RPM's and Output.

Edit 1: Sam, after reading your mail...I realized something...on the Group Windings...we are spreading the magnetic fields...not as compact as in Pairs all north...therefore, we need to either add same wire than pairs, per coil...or use heavier gauge to make fields stronger (per coil) at Group Winding.

Powered both brush sets the same battery: 3900 rpm, amps on the firsts coil dropped to .7A.

Couldn't get a reading on the amps on the other coil for some reason. (Multimeter issues?, tried 2 or 3), but even so looks like rpm went up and amps stayed the same if you figure both coils were taking the same amperage. I could stop the motor with my fingers on one coil, probably not on 2. Pretty interesting how much the amps dropped on the one pair. Try to get some video soon
My Quad stator pentagon winding motor did 7500 rpm on one brush set if I remember right, drew 2.5A, 8600 with 2 brushes. I think I had .7 ohms per brush set though, got up to 130 dF the day I blew a brush set, used solder. so it needs reworked.

This motor is too stiff to turn yet, no where as loose as my QP10. Gotta look at brush tension again, pretty sure it isn't binding. If the brushes are sharing the amperage equally then I got more rpm for the same load when running both sets in parallel. The commutators are looking kinda dirty too.
You can see my QP10 run on UFO's site where I earned honors for that job!
So working toward some better results...
