Hello All,
I'm doing a retrofit on an EMCO F1 mill. Has anyone
successfully used the original steppers? I have built Hans
Wedemeyer's driver outfit which works fine with other steppers I
have, but the mill motors do not do well. Hold torque seems OK but
when running the shaft can be stalled with the fingers. The motors
are Superior Electric SM-072-0060-DS types, 6-wire, with 4.7 ohms per
winding leg.
Best Regards
