3 tips for replacing stepper motor with servo motor

1. To ensure that there is not too big change in control system, it is suggested to choose digital servo system, which can still use the original pulse control method.
2. As the overload capacity of servo motor is strong, 1/3 of original stepper motor rated output torque can be as reference to determine the servo motor rated torque.
3. Since the rated speed of servo motor is much higher than stepper motor, it is better to add a deceleration equipment, so as to make servo motor run at rated speed. To reduce the cost, it is also feasible to choose the motor with smaller power.
