I'm still trying to get a handle of finding the right motors, (everytime I think I understand what's involved, my mind goes blank when start trying to do the calculations, eek), and I noticed that a lot of motors available don't have torque/power curves available.

So, if I find a motor with curves available and the NEMA size, voltage, amps and inductance specs are close, can I use that curve to do some calculations?

Thanks,
BobL.
