Computer interfacing
This makes the stepper motor suitable for industrial
applications in such things as automatic lathes, milling
and drilling machines, X-Y co-ordinate tables and other
positioning mechanisms. This is in addition to the com-
puter applications already discussed.
Advantages of stepper motor systems
The major advantage of stepper motor systems is that
control is open loop, so avoiding the problems of closed
loop control. All that is needed is a counter (software or
hardware) that counts the number of pulses from the
start. The speed of rotation is controlled by the fre-
quency of the pulses, and the acceleration is determined ...
