Unipolar (of one polarity) is the fundamental characteristic of internal signals in digital communications equipment. A unipolar signal represents simply, one of two states: on or off; 1 or 0. A unipolar signal may either: go on for the portion of the bit time, and then return to zero state (unipolar RZ); or, go on (and stay on) as long as consecutive one bits are present, not returning to zero until a zero state occurs (unipolar NRZ). Contrast with bipolar.

| unipolar |
A bifilar wound motor. The current flows only in one direction through each winding. Normally there are two winding per bobbin and eight bobbins per motor. Usually is a 5, 6 or eight wire motor. One or more common leads are used per winding. Has less torque than a bipolar stepper motor but is simpler to drive. Bipolar stepper motor- just two windings. The electronic controls reverse the current alternately between the coils. This motor has more torque but requires more electronic controls.
