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:
• If the stepper motor works at resonance region, the resonance region can be evaded by changing mechanical transmissions such as velocity ratio.
• Use subdivided driver, which is the most common and simple method.
• Replace for the stepper motor with smaller stepping angle, like 3-phase or 5-phase stepper motor.
• Replace for AC servo motor, which can nearly overcome vibration and noise, but the cost is quite high.
• Add magnetic damper to the shaft of motor, such product has been available in the market, but the mechanical structure is changed a lot.

Advantages of Stepper Motor:

• 1. The rotation angle of the motor is proportional to the input pulse.
• 2. The motor has full torque at standstill.
• 3. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is noncumulative from one step to the next.
• 4. Excellent response to starting, stopping, and reversing.
• 5. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
• 6. The motor’s response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
• 7. It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
• 8. A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
