The large vibration and noise of the stepping motor at low speed is its inherent shortcoming. Generally, the following solutions can be used to overcome:
A. If the stepper motor works just in the resonance zone, the resonance zone can be avoided by changing the gear ratio and other mechanical transmissions;
B. Using a drive with subdivision, this is the most common and easiest method;
C. Change to a stepper motor with a smaller step angle, such as a three-phase or five-phase stepper motor;
D. Switching to AC servo motor can almost completely overcome vibration and noise, but the cost is higher;
E. A magnetic damper is added to the motor shaft. This product is available on the market, but the mechanical structure changes greatly.
