Finagle's law says 90% of my 3-phase big iron was acquired in the USA
and expects 3-phase 60Hz 208V... :-(
Many machines which did NOT have a ferroresonant transformer
could be run from 50 or 60 Hz with no problem. The one
place it was a problem would be getting the disk spindles
turning at the right speed.
Matching the available voltage would be the other detail,
but a standard voltage adjusting transformer would do it
fairly simply.
But, the ferroresonant transformers needed the right frequency.
