The silent drive of the stepper motor is realized by controlling the current waveform of the stepper motor driver. In normal drive mode, the stepper motor makes noise because of the vibration and resonance caused by the current mutation.
By controlling the rising and falling slope of the current waveform, the silent drive technology can reduce the vibration caused by current sudden change, so as to realize the silent drive.
By using the high-precision current control algorithm and the intelligent control chip of the driver, the silent drive technology can effectively reduce the noise of the stepper motor and improve the working efficiency and accuracy of the stepper motor.
