Re: Stepper motor connection

Now you got my curiosity aroused. What's the mechanical reason?
Isn't it simply one step per pulse. Are you saying one or both might miss a step?
My application could be described as 'gross movement' however it still needs to maintain step accuracy. It will move from one point to another with little load change. I will try to balance the arms so it has similar load both directions.

As for connection, I would think series would keep the current through both motors the same hence 'same torque'.
