RE: Need an Electric Motor
How close does it need to be to 14K RPM?
A Mega 22/30/2 Geared 2:1 on 18 cells will turn the 12X3 at ~13940 RPMs.
Add another cell to 19 and it goes up to 14405 RPM
The 22/30 is good to 70 amps and this would put it in the 56-59 amp range.
Jeti 45-3 Direct Drive on 21 cells 50 amps $ 14100 RPMs.
