ABSTRACT
The circuits and programs presented in this chapter relate to unipolar motors. Chapter 18 is devoted to basic circuits and programs for driving bipolar motors. The reader should keep in mind that unipolar motors can be used with bipolar circuits by ignoring the center taps, which can be left floating. The same is not true of bipolar motors, which require variations in the current polarity and, therefore, are not compatible with unipolar circuits.
