You actually don't want big capacitors for this unless you're gannging multiple disks to work in unison.

Ideally, you would find the max speed that you are willing to opperate the disks at, then you would use a variable capacitor to tune the pulsing to 60 HZ so that you could just run it through a step down transformer transformer to drop it to 120 or 240 V.
