Late 1980's vintage Yaskawa Minertia, 5th axis servo runs fine at the faster speeds but at slow speeds it either turns in "steps" or not at all (this, under no load with motor removed) Brushes have plenty of length, everything very clean, no oil or dirt anywhere. Cap on rear end contains optical encoder.
With power removed, nearly impossible to turn by hand...is that the way it should be ? (but when turned with wrench it feels smooth...just surprisingly difficult to turn)
Weight is 7.5 lbs
