Scientific American, back in June 1958, covered many details of 
Foucault pendulums, from Charron pivots to drive systems. The article 
was later reprinted in "The Amateur Scientist" book. It describes a 
magnetic drive which applies force near the pivot and another which 
sits underneath the pendulum.

There's also a mechanical drive, as described near the bottom of this
