At any rate, I still agree with Tyke's conclusion - don't do it.

On the other hand: Fan motors are sometimes made slower by putting a
transformer in, sometimes even biggish (several kW) three-phase fan
motors are slowd by adjustable three phase transformers. (Seen that
once when a cooling fan of that type used to cool some delicate
electronics blew so much air that the airflow made the electronics
boards vibrate too much, so the fan had to be slowed down, and an
electronic dimmer was out of the question because of the
electromagnetic noise it would produce...)
