No matter how small the power of the motor is, it will also produce noise when it is in use, such as the 12v Stepping Motor is no exception.The following are some methods to reduce vibration and noise. The vibration and noise of a stepper motor at low speed are its inherent disadvantages, which can be generally overcome by the following schemes:
A. If the stepping motor works in the resonance region, it can avoid the resonance region by changing the deceleration ratio and other mechanical drives;
B. Use the drive with subdivision function, which is the most commonly used and easiest method;
C. Replace it with a stepper motor with a smaller step Angle, such as a three-phase or five-phase stepper motor;
D. Alternating current servo motor can almost completely overcome the vibration and noise, but the cost is high;
E. Add a magnetic damper to the motor shaft. Such a product is available on the market, but the mechanical structure has changed greatly.
