Stepper motor running jitter how to do? What are the solutions?

Stepper motor is widely used, production life are useful to, many friends often have asked a question, that is, the stepper motor running jitter, because I do not know the specific reasons, more trouble, then why stepper motor running jitter? Vacuz to give you an introduction!

In fact, the stepper motor rotation jitter is a common phenomenon, but can be avoided. Stepper motor in the input drive pulse, the rotation will be vibration, when the rotor’s inherent vibration frequency and drive frequency divergence will occur when the resonance phenomenon, the vibration if the larger, the motor will be out of step and discontinue the phenomenon, and even the onset of mis-step or reversal of the phenomenon, the resonance frequency of the stepper motor is usually in the 100 ~ 200H left.

Stepper motors have a fixed resonance area, four-phase induction sub-stepper motor resonance area is generally between 180-250pps (step angle of 1.8 degrees) or in about 400pps (step angle of 0.9 degrees), the higher the motor drive voltage, the higher the motor current, the lighter the load, the smaller the motor volume, the resonance area upward shift, and vice versa, in order to make the motor output torque is large, not out of step and The noise of the whole system is reduced, the ordinary working point should be offset from the resonance zone.

When you encounter the stepper motor chattering at startup and not running, chattering in operation, chattering at low speeds and so on, according to our engineers over the years of work experience summed up, the first to bear the brunt of the stepper motor selected small, other causes and stepper motor chattering treatment methods are as follows.

1, the motor is selected small, inertia is not enough, the treatment is to change the corresponding type of motor.

2, the current is set small, the current is set to the corresponding value.

3, the knob is not adjusted, the knob will be adjusted to the appropriate gear.

4, in the resonance area, the initiative to adjust the subdivision or bypass this area.

5, motor wiring errors (mainly 8-lead motor), the motor leads connected to the right.

These are the causes and solutions to the jitter when the stepper motor rotation, master these basics, help to better use the stepper motor!
