The 34014 motor will produce the same torque at a somewhat higher speed
than the 34013 motor, because of the lower resistance and inductance.

However, both of these motors will be severely limited at higher speeds
due to the high resistance. For a 1076 Oz-In motor, you really want a
super-low
resistance motor, with perhaps a rating of 7A / phase if used with Gecko 201
drives, or even higher if using drives capable of greater current.

I'd take a wild guess and say that even the 34014 motor will run out of
torque
well below 1000 RPM.
