I am looking for information regarding the torque fall off of stepper motors over the RPM bandwidth they support.
Specially Mach3 -> Gecko -> 600-1800Oz/Inch motor.
My focus is on the range between 0 and 800 RPM. 0 is easy, that's the rated holding torque.
After that it goes down hill. But how fast? Guesstimations range from 20% to 65% left at 1000RPM.
Any pointer to more information or where to find motor curves would be great.
