Bipolar motors
Bipolar motors have a single winding per phase. The current in a winding needs to
be reversed in order to reverse a magnetic pole, so the driving
circuit must be more complicated, typically with an H-bridge arrangement (however there are several off-the-shelf driver chips available
to make this a simple affair). There are two leads per phase, none
is common.
A typical driving pattern for a two coil bipolar stepper motor would be: A+ B+ A− B−. I.e. drive coil A with positive current, then remove current from coil A; then drive coil B with positive current, then remove current from coil B; then drive coil A with negative current (flipping polarity by switching the wires e.g. with an H bridge), then remove current from coil A; then drive coil B with negative current (again flipping polarity same as coil A); the cycle is complete and begins anew.
Static friction effects using an H-bridge have been observed with certain drive topologies.
Dithering the stepper signal at a higher frequency than the motor can respond to will reduce this "static friction" effect.

Longer Life
Stepping motor is a mechanical structure,which does not need be changed by electric brush or Hall sensor,thus reducing the probability and increasing the motor life.Stepping motor life usually determined by the life of the bearing.

Applications of Stepper Motors
s
Computer controlled stepper motors are a type of motion-control
positioning system. They are typically digitally controlled as part
of an open loop system for use in holding or positioning
applications.
In the field of lasers and optics they are frequently used in
precision positioning equipment such as linear actuators, linear
stages, rotation stages, goniometers, and mirror mounts. Other uses
are in packaging machinery, and positioning of valve pilot stages
for fluid control systems.
Commercially, stepper motors are used in floppy disk drives,
flatbed scanners, computer printers, plotters, slot machines, image
scanners, compact disc drives, intelligent lighting, camera lenses,
CNC machines and, more recently, in 3D printers.
