The stepper or stepping motor produces rotation through equal angles,
the so-called steps, for each digital pulse supplied to its input. For
example, if with such a motor 1 input pulse produces a rotation of 1.8 ~
then 20 input pulses will produce a rotation through 36.0 ~ , 200 input
pulses a rotation through one complete revolution of 360 ~ It can thus be
used for accurate angular positioning. By using the motor to drive a
continuous belt, the angular rotation of the motor is transformed into
linear motion of the belt and so accurate linear positioning can be
achieved. Such a motor is used with computer printers, x-y plotters
robots, machine tools and a wide variety of instruments for accurate
positioning.
