How come some 34mm length Nema 17 steppers have a rated current of 0.4A while others have a rated current of 1.4A?
These two seem to have the same torque.
The 0.4A one has much higher phase resistance and phase inductance whatever those mean.
I'm considering buying the ones in this link because they're the cheapest i could find but i'm wondering if they'll perform as well as well as 1.4A ones.
