Are any of the wires touching when you try to spin it? My Vexta steppers are nearly impossible to spin if some of the leads are touching each other. When I separate them they feel fine.

Hi all,

I am trying to test my latest set-up and found one of my e-bay steppers
is locked up.

NEMA34 single stack, and I have a tough time spinning it by hand.
It's one of those high tech manufacturers, ASTROSYN !
(yeah, I never heard of them before either)
Minebea Co. Ltd, Thailand

1.7 V, 4.7 A and in series mode, my Gecko can get it to spin at about
100 to 200 er.... 0.1 to 0.2 hertz

Iwant to open it up and look at the bearings, but am not sure if I am
better off trashing it and getting a new one, or trying to fix this
one.

looking for recommendations.

Dave
