Hello again.
Assuming a stepper motor can be wired either way, what are typical reasons
for wiring a stepper motor as Unipolar or Bipolar ?
Thanks !

unipolar: easier to drive because you only need 4 low side switches

bipolar: more powerful because there are more windings powered at a
time

lower power consumption


twice the power consumption of unipolar.
