Differences between Stepper Motor and Servo Motor:
Stepper Motors have a large number of poles, magnetic pairs generated by a permanent magnet, or an electric current. Servo motors have very few poles; each pole offers a natural stopping point for the motor shaft.
The torque of a stepper motor at low speeds is greater than a servo motor of the same size.
Stepper motor operation is synchronized by command pulse signals output from the pulse generator. In contrast, the servomotor operation lags behind the command pulses.
