It's good you found the right version .. and kinda weird that the newer firmware does bad things.

I'm considering getting the newer board (SMT) so I can use that as the main traction motor controller, then couple the shafts with the old one and use it as a regen / dyno. If I measure the amount of power going into the battery pack, I should be able to 'guestimate' the power output of the unit. This all hinges on how much brake torque the regen can generate.
The testing I did with a DC motor (and Paul's DC controller) coupled to an AC motor (and Paul's AC Controller) leads me to believe that you generate power with regen down to a certain speed. Like maybe 500 rpm. Lower than that it actually draws power from the pack to stop with regen.

Worst case scenario I have a prius IPM motor that I can rectify and variably load dissipate since it doesn't really require a controller to regen.

I also wanted to play with the IPM motors as traction motors. I didn't see resolver the encoder boards for sale. Anybody know if these are still available?
The resolver to encoder boards were there last time I looked. Maybe Paul ran out and has not re-ordered the boards?

IPM motors as traction is interesting ... let us know how it goes!
In THEORY there is no difference between Theory and Practice
