I'm not sure what a prony brake is, but would this
work?

I've been wanting to buy one at work for a while. It's
a device that replaces a motor coupler and VFD at the
same time. They use big high powered rare earth
magnets in combination with a big copper disk to
create eddy currents. What more could a mad scientist
want?

   An interesting product.  Any idea what the prices are?  One 
problem I wondered about is the heating due to slip and didn't find 
it mentioned at their site, although it might be there.  I would 
think this is the sort of thing that would have interested Tesla.
