The vibration and noise of the stepper motor at low speed are its inherent shortcomings, which can generally be overcome by the following technical solutions:
1、Use a drive with a subdivision function, which is the most commonly used and easiest method;
2、If the stepper motor works exactly in the resonance region, it can avoid the resonance region by changing the deceleration ratio;
3、Change to a stepper motor with a smaller step Angle, such as a three-phase or five-phase stepper motor;
4、Replaced by AC servo motor, can almost completely overcome vibration and noise, but the cost is higher;
5、Add magnetic dampers on the motor shaft, this product is already on the market, but the mechanical structure has changed greatly.
