Servo motor and stepper motor are almost
used in all automated industries where high precision is
to be achieved. Though servo and stepper motor can
provide adequate torque with high accuracy, it is
prominently important to choose the best one based on
the performance ratio of these two motors. The decision
for picking out the most appropriate of the two
alternatives has many criteria. Hence the technical
parameters such as speed, Torque, acceleration and
competitive price are focused in this paper.
