Hello,
I have an 8 wire stepper motor (unipolar i'm assuming) in which the wires are grouped into 2 sets of 4. I have successfully determined
which wires correspond to the coils. I can also make the motor step.
However, I can only make the motor step using the 1st set of 4 wires.
The second set of 4 wires seems to do nothing at all (even though
current passes through just fine). I thought maybe that this was due
to the fact that I am energizing each of the 4 pairs (1st set and the
2nd set) in the wrong sequence. This is where I get even more
confused, because the 1st set of wires also seems to make the motor
behave like a bipolar stepper. That is, I energize the first pair
then the other, then switch the polarity and do the same again and the
motor takes 4 steps in total (in the same direction). Huh? Has
anyone ever encountered this kind of behaviour before?
thanks! julia
