I've got two motors right now that I'm planning on trying.
-Turnigy AquaStar T20 (229amps Max Load)
41V Max (I'll be running 36V)
1280 RPM/V or 730 RPM/V
So a max for my configuration of 46K RPM
-Turnigy SK3 EDF (110amps Max Load)
30V Max
1500 RPM/V
Max of 45K RPM
There are a lot of considerations here though. First the max RPM's are theoretical no-load speeds, and I have reason to believe the specs for the Aquastar are not correct. Pretty safe to assume the actual RPM will be less then the max possible for that motor.
I'm also continuing to look at different motor options so if anyone sees something that might work let me know. Keep in mind we're looking for around 45K+ RPM and over 100 amps max load, probably closer to 150 amps.
Edit: Another consideration is shaft diameter. For my current design the shaft diameter needs to be greater than 6.5mm and then will turned down to the fit the compressor wheel.
