How to reduce vibration and noise of the stepper motor?
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.
