• •The motor has full torque at standstill(if the windings are energized).The rotation angle of the motor is proportional to the input pulse.
• •Precise positioning and repeatability of movement since good stepper motors have an accuracy of ¨C 5% of a step and this error is non cumulative from one step to the next.
• •A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
