===Features===
# The rotation angle of the motor is proportional to the input pulse.
# The motor has full torque at standstill(if the windings are energized)
# Precise positioning and repeatability of movement since good stepper motors have an accuracy of – 5% of a step and this error is non cumulative from one step to the next.
# Excellent response to starting/stopping/reversing.
# Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
# The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
# It is possible to achieve very low speed synchronous rotation with a load that is directly coupled to the shaft.
# A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
