•
The shaft of a stepper motor moves
between discrete rotary positions typically separated by a few degrees.
•
Stepper motors - excellent for
applications that require high positioning accuracy.
•
Stepper motors are used in X-Y scanners,
plotters, and machine tools, floppy and hard disk drive head positioning,
computer printer head positioning, and numerous other applications.
•
Have several electromagnetic coils
that must be powered sequentially to make the motor turn, or step, from one
position, to the next.
