hi chaps (if anyone is still here)
When you turn a stepper motor with no current flowing it resists turning. Anyone know what that property is called?
Also, is there such a thing as a stepper motor which doesn't resist turning hen no current is flowing?
eg a stepper attached to a ballscrew moving an axis on a machine - put a handle on it - can you get a proper feel to the motion, or do yuo have to put up with the lumpiness?
