Yes. I did that to see how the brushes are timed. It spins the same speed either way, so I am assuming that the brushes are neutral.

What I meant was this "field control module" is a very simple device with no other purpose than supplying 12V and suppressing the spike when turned off. I am a bit skeptical that it will work well because if it was this easy to control a sepex motor with a PM/series controller, you would see it all over a Google search, but you don't.

I am also starting to think that my motor is too small. It just looks...well..small.
