How to overcome the vibration and noises of 2-phase hybrid stepper motor when rotating at low velocity?

The vibration and noise of the stepper motor rotating at low velocity its the intrinsic defects, which can be generally overcome by adopting following schemes:

1    1. If the stepper motor works at resonance region, the resonance region can be evaded by changing mechanical transmissions such as velocity ratio.

      2. Use subdivided driver, which is the most common and simple method.

      3. Replace for the stepper motor with smaller stepping angle, like 3-phase or 5-phase stepper motor.

      4. Replace for AC servo motor, which can nearly overcome vibration and noise, but the cost is quite high.

5    Add magnetic damper to the shaft of motor, such product has been available in the market, but the mechanical structure is changed a lot.
