Tips: Low frequency characteristics of servo motor and stepper motor
Stepper motors are prone to low-frequency vibration at low speed. Vibration frequency is connected with load conditions and drive performance. Meanwhile, it is generally considered to be half the motor's take-off frequency in no-load condition. This low-frequency vibration, which is determined by the working principle of the stepping motor, is very unfavorable for the normal operation of the machine. When the stepper motor works at low speed, damping technology (such as adding a damper on the motor, or the use of subdivision technology on the drive) should generally be used to overcome the phenomenon of low frequency vibration. The AC servo motor operates very smoothly and does not vibrate even at low speeds.
AC servo system with resonance suppression function can cover the lack of mechanical rigidity, and the system has a frequency analysis function (FFT), which can detect the mechanical resonance point and is convenient for system adjustment.
