Well, how about replacing one of the variable diameter pulleys with a larger diameter one? I've bought such things from McMaster/Grainer/MSC before to change the rotational speed on HVAC units.
Yeah, they're fairly new, at least at relatively low prices. The electronics used to be really expensive because the small semiconductors couldn't take the power/current. But with the advent of...
Yeah, my bad - that was a poor example. But you can get VFDs that are 3ph in, 3 ph out, 1 ph in, 3 ph out, and 1 ph in, 1 ph out. Here's a better example:

By the way, it is possible to slow down a single-speed permanent magnet, split-phase or other single-phase motor with a modern VFD. They work by slowing the 60 Hz frequency of the AC power and...
