    Tips: Servo motor vs. stepper motor

    The control methods of stepper motors and servo motors are different. The stepper motor controls the rotation angle by controlling the number of pulses. One pulse corresponds to one step angle. However, because there is no feedback signal, the motor does not know where it is, and the position accuracy is not high enough. The servo motor also controls the rotation angle by controlling the number of pulses. Each time the servo motor rotates one angle, a corresponding number of pulses will be sent out, and the drive will also receive the feedback signal, which is compared with the pulse received by the servo motor. In this way, the system will know how many pulses are sent to the servo motor and how many pulses are withdrawn at the same time. In this way, the rotation of the motor can be controlled very accurately, thereby achieving precise positioning. The accuracy can reach 0.001mm.
