Stepper motor at low speed is easy to appear low frequency vibration phenomenon. Vibration frequency is associated with load and drive performance, it is generally 3 phase induction motor believed half frequency vibration frequency for the motor no-load takeoff. This determined auto spare parts by the working principle of single phase motor stepper motor in low frequency vibration phenomenon is very bad for the normal operation of the machine. small diesel engine When the stepper motor work in low speed, general damping technology should be adopted to overcome the low frequency vibration phenomenon, ac synchronous generator such as add single phase induction motor damper on motor, or drive the segmentation technology, etc. Ac servo motor running smoothly, even in the low speed also won't appear when the vibration phenomenon. Ac servo system has a resonance acmotortrading.blogspot.com suppression function, can cover the mechanical rigidity, and internal system has the function of frequency squirrel cage induction motor resolution (FFT), can detect the mechanical resonance point, is advantageous for the system adjustment.
