[TriEmbed] Stepper Motor

[Jeff Highsmith]

Brian,

Looking at the picture, I see the shaft is offset, meaning this is most likely a geared motor. Not all gear sets are "back-driveable", so the resistance to hand-turning may not be an indicator of the motor's condition. 

Jeff :)

When I try to run them from my Pi (I have the controller and code) I can feel them trying to move.  Ready for the trash can?
