Voice coil control

Hi,

I am developing a light weight stabilization system which uses a voice coil actuator for counteracting vibrations.

I am wondering if I can use the driver from inside a digital servo to drive the VCA instead of the DC motor in the servo. The servo outputs PWM 5v to the motor at 300 pulses per second.

Has anyone had experience of this sort of setup? Can anyone advise me if it's likely to work before I spend £150 on the VCA?

Any help much appreciated.

Thanks

300 Hz is awfully slow for voice coil control. I've run as high at 80 kHz to get very tight control with voice coils.
