Vibration and noise is the inherent shortcomings of stepper motors, when they are rotating in low speed, generally we can adopt the following solutions to overcome:

A. For instance, a step motor is working in resonance district, it can avoid resonance district by changing reduction ratio and other mechanical rotation.

B. There is also a commonly used and easiest method, that is to match a driver with subdivision function.

 C. Using a step motor with smaller step angle, such as 3-phase or 5-phase stepper motor.

D. Exchanging into servo motor, it can almost overcome vibration and noise completely, but the cost is too high;
