Update for Sep 21

Here are the raw files, put in a zip file so I don't have to split them up. There is video as well but it will be a while before I get that done.

Summary:
The encoder is working quite well now. No issues with losing speed sync ... not sure why. It likely has to do with cable routing (noise issues) but could also be the number of pole pairs

Pole pairs is 4. The rpm works out quite well - my lovely wife found my rpm meter so I cross-checked the rpm during the tests

run-rotor-test gave me very low numbers compared to my previous tests with 2 pole pairs. The current to the motor was lower, and the best results were the last set in the set of 50.

I had the motor over 4000 rpm - no issues with the motor. Issues with my encoder coupler, but none with the motor or controller.

The control is much less aggressive with 4 pairs of poles for some reason. Acceleration takes quite a while.

I need a manufacturer and a part number for the round 12 pin connectors in order to get parts - female connector and pins. I am still using the temporary setup.

I got a couple of decent 10 turn 5K pots to use for the throttle before my hall effect throttles arrive. I'm still trying to source them locally - shipping and customs from digikey and mouser kinda suck.

I also got some small pins for the encoder that should work better than what I have right now. I'd like to get the encoder built into the motor working properly.
