Nice to see the Casablanca listed - I had a beautiful one - spent the big bucks for it and it worked flawlessly for 17 years and sold (sob) with the house. It was a large stack metal ring set - and had three speeds that were provided by the use of high tech - oh - capacitors - that changed the impedance and allowed more or less current to flow - and current drives the motors via magnetic field strength.
