Re: Unipolar or Bipolar?

Dave,

Many thanks for your response and clarify my concepts about
unipolar/bipolar.

As understand apply high voltage to the motors with bipolar
configuration is better than unipolar controller even with the same
high voltage.

If I use microstepping with bipolar, I obtain smoother response, but
what happen with the maximum speed, is same that full step or I am
wrong?
