Electrostatic Influence Machines

[Jdo300]

Hi,

I've been doing some reading on electrostatic influence machines like this one here called Nicholson's Doubler:

I was wondering if there is any drag force or back attraction/repulsion torques that the rotating disks would experience as the operator rotates the handle.

Thanks,

In case the first link I posted doesn't work, here's an alternative (and more general) article about influence machines here on Wikipedia:
