Thanks Matt,
I do remember you mentioning them when we last met but that had not come back to me, how SLOW can they run? any ideas on how to find out more info on them? I am guessing this is an AC motor with some form of pulse width modulation, will have to add that to my searching.
EDIT: the technology to do variable speed drives looks like it might be a LARGE source of RFI, which I need to avoid having near the antennas.

Slightly off topic but have you considered a variable speed drive (variable frequency drive)?
The ones i have used have been totally adjustable in many respects, one also incorporated dc breaking.
just a thought.
