That's all a question if you can get enough inuctivity in the Windings for
the Voltage/Frequency you want to use it. The Magnetic Flux in the Core

In general you can power 50 Hz equipment from 60
Hz. But you have to be
careful about powering 60 Hz equipment from 50 Hz - the transformer may
saturate. Don't even think about powering 400 Hz equipment from 50 Hz or
60 Hz.
If the operating voltage is adjusted, you can actually use those things.
I found that a 110V 25Hz induction-motor fan will run fine (but at
twice the speed) on 230V 60Hz. Similarly, I used 115V 400Hz
transformers with 12V 60Hz power successfully. Whether or not you can
find a 400Hz transformer with the proper turns ratio is another matter,
but I forget what I used mine for (could have been for a low-voltage
filament supply)--but it worked.
See, for example:
