First spin of the Warp9 powered by the P&S 500 amp, or cougar controller, was successful!
I'll edit this post to include links to the youtube videos when I get them done and posted, and will post the data capture from the controller (rtd-period 100) maybe tomorrow.
The warp9 turns fine. It is coupled (poorly) to a Siemens AC motor. The alignment is not very good and it makes a lot of noise. The battery amps on the pack did not go very high, since there was no real load.
The positive motor cable had more corrosion than I thought. Initially, the motor would not turn at all. When the controller output got up to about 30V it sparked through the corrosion (with a bad noise - BANG - and a bad smell - ozone). I took the connection apart and cleaned everything up. It appears to work better now.
