What is the best/safest way to wire a 200V fan in the USA, using 120v or 240v?
The choice of 200 VAC is curious, I have not encountered this voltage before on a motor. 208 VAC is a reasonably common power standard in some parts of North America. This motor would probably be fine operating on that voltage as it is only 4% different.

Your options for running this motor are, from best to worst.


Get 208 VAC power to your premises. Unless you have it already, this is cost prohibitive in most places.
Get a transformer that converts 120 VAC to 200 or 208 VAC 60 Hz single phase. This should exist, although I haven't purchased one before.
Run the motor with a series resistor in the high speed from 240 VAC single phase 60 Hz power. The motor would normally draw about 0.65 amps in high speed. This corresponds to an impedance of around 307 ohms. You can use a resistor of approximately 61.5 ohms in series to drop the 240 VAC to 200 VAC.


Option #2 is the most practical.

Option #3 is simply tolerated by most motors of this type, it is the least desirable option. The motor may have a very large startup time if you do this. Also note the resistor will generate around 25 watts of heat and need to be rated as such.
