Re: inexpensive nema 17 "closed loop" stepper driver
I'm surprised to still see the usage of NEMA as a power reference for steppers/motors, NEMA is a mounting frame size and has not alot to do with power.
For e.g. I have catalogues for a couple of the very large Stepper manufacturers, they have certain NEMA size motors with different core (body) length, each one has a different Nm torque value, but have exactly the same (NEMA#) mounting .
