what is the deal about midband resonance damping?

[brutto]

hi all,

could anyone tells me about what is the deal about midband resonance damping? i means, when i gets the frequency where the motor is in the resonance zone (midband), what must be done? limit voltaje (i think the resonance comes and the voltaje is going up), change frecuency (motor is in it's natural frequency zone), add in a coil the angle lossed in the other coil?

i have read some threads about midband resonance but noone says what must be done, only says about you can add an antiresonance circuit or add an algorithm to the gates, but what must be done in the effect? (electric effect, not mechanical like change inertia rotor).

thanx in advance and sorry my english.

If your steppers are dual shaft, adding dampers is very easy and works great.

hi, i would to know about electronic midband damping.
