 just purchased a Bergmann fan that runs on 220/ 50  cycle,, Amazon sells stuff to convert 110 to 220, but it will still be 60 cycles, since it's a fan motor, my thinking is it shouldn't matter,  but it could throw the timing off.   I am placing the fan in my game room where it may run for  a few hours  straight ...I don't want to mess it up...  has anyone ever put something together thats compact that would fit in a small place so the fan would be normal looking and not plugged into some big giant box.. I guess it's not a big deal... also would it be a crime to possibly have the motor re-wired for 110 .... and if I did that would I be cast out and shunned..

No personal experience with it, but plenty have and they seem to do fine, see below.


 


I've never seen a "small" cycle converter, I have a large one for a 125 Cycle Pancake I have and I think I had it out once, not as much fun as it seems...

50 cycle running on 60 cycle will not hurt the motor the only
difference is it will run faster. I have a century S4 that’s 50 cycle
And it runs very well stays cool runs faster due to cycle difference
However, you can’t run 60 to 50 it’s only one way. Your fan will do very
Very well on 60.

If you want to see it run on 220/50, bring the fan to Fan Fair and we can run it in the shop.

I have a 1900 GE pancake rated at 104 volts,125 cycles. It seems to be happy at anywhere from 80-120 volts on a variac without getting warm. I basically use it as a speed switch. Any worries?

Pull the back cover off and see how many poles the fan has. GE pancakes that are 125 cycles would be an 8 pole stator. I've never been able to run 125 cycle fan on half voltage like some recommend.

I have run my Interior Conduit AC fan rated at 52 volts and 14400-18000 ALTS (I think that is about 125-133 cycles) on my variac with the motor staying cool for probably at least an hour.   Dial in a speed that seems normal or a little less and watch for any overheating issues.   I don't remember the voltage my IC fan was happy with but I did start at 52 volts and, possibly, it ran well up around 100-120 volts, just don't remember.
