Use the largest 70.7 volt audio amplifier you have and feed a variable frequency sine wave generator into it. Sweep the oscillator's output down to the speed your director likes (If she likes a different speed tomorrow, no problem).We have out a ceiling fan on set. It is thee speed but even the slow setting is too fast for the director. We can't feed it from our varactor dimmers so how do we slow it? Would a variable rheostat work?
Ah. That is very interesting. We have regular fan assembly up now so have a commercial fan controller on way. They'll have to run it stage side fort his show. But! I'll get one of those motors and Attach fan blades for future. Can also see other DMX apps (Like a Dutch windmill etc.) Rons reply actually gets down to the physics of the fan motor which is good to know.
I got a so-called motor controller, but it must be a varactor because it - like a dimmer - didn't slow the fan down even at the lowest setting.Ah. That is very interesting.

I didn't connect the dots, but that is brilliant. Not that I'd expect any less from @RonHebbard .Precisely Ron's suggestion, in fact, done on a budget.
