How can incidences of resonance be suppressed?
Tips and tricks!
· Half step instead of full step.
Half step here is better than full step. The two−phase stepĆ
ping motor shows generally good run characteristics at
half step.
· Set phase current lower (to the value actually required).
While this reduces the system’s stiffness, it also reduces
its tendency to oscillate.
· Operating frequencies not equal to resonance frequenĆ
cies.
The operating frequency is often near the resonance freĆ
quency or is a multiple of it. Small deviations from the
"critical" step frequency usually show good results.
· Make the acceleration ramps steeper.
The stepping motor is "pulled" through the critical areas
quickly and so does not tend so quickly to oscillate.
· Increase the friction (emergency solution)
Friction dampens the entire system, but useful torque is
lost.
