Hi all,

how to find a transfer function that gives me the acceleration response of a voice coil actuator as a function of the input current. I found about electrical and mechanical time constants in the datasheets, but how do i use them? the actuator is only loaded with a mass. nothing else.

Thank you in advance for your help!

Bob
