There are two types of labeling motors for common labeling machines. One is a stepper motor and the other is a servo motor.
The functional parameters of the two are compared as follows;
1. Comparison of motor rotation speed; (Note: speed estimation is for reference only)
Stepper motor: 1000 times, it takes 300-400 milliseconds;
Servo motor: 1000 times, it takes 5-10 milliseconds;
2. Comparison of labeling accuracy;
Stepper motor: The ideal precision is 1-2 mm; (open loop is uncontrollable, the accuracy range has a great influence)
Servo motor: accuracy is ±1 mm; (closed loop controllable, high precision and stable)
