Hi Glen, I've found when winding parallel , if they short to each other, it will cause slow rotation and heavy draw.
You are probably shorted somewhere.
I wound Matts with ~17 guage , a single strand,all I had, but my windings amp draw is too high. Need to find some wire.
I think slip rings for each individual set of coils, instead of a commutator, is whats needed.
Commutators' always have overlap, unless you leave a blank.
The blank is too big. And they should not mix.

As one coil is dropping, the next has to be climbing.
Climbing creates an opposite reaction, dropping creates an opposite reaction.
They have to work together. It's the same as Matts' Bouncer.
Sorry just getting sidetracked.
