How to reduce vibration and noise of the stepper motor?

2015-09-01

Stepper motor rotates at low speed, with vibration and noise, it is inherent shortcomings, here are the solutions to solve it:
A. if the stepper motor work on resonant zone, can change the reduction ratio and other mechanical transmission to avoid the resonance region;
B. it is the most commonly used, the easiest way to use the subdivision function driver;
C. By changing the smaller step angle of stepper motor, such as 3-phase or 5-phase stepper motor;
D. If change to ac servo motor, can almost overcome the vibration and noise, but the cost is higher;
E. can add magnetic damper on the motor shaft, this product already in the market, but the mechanical structure have changed a lot.
