The important point here is the motor rating. If its rated at 200oz/in then it doesn't matter what type it is, its 200oz/in.
However, if you take a 200oz/in unipolar and wire it for bipolar then you get more torque out of the same motor and its no longer 200oz/in. To get that extra torque you sacrifice some micro-stepping ability - where you had four windings you now have two - not as many combinations to position the rotor. |
