Help: converting 230V (1ph) 50Hz machines to run on 220V (1ph) 60Hz supply

[deema]

The simplest solution is to fit a single phase to single phase inverter. This will take 220v 60hz in and convert it to 240v 50hz out. Just pick one large enough for you biggest machine. Not cheap, but it’s the optimum solution.

I’d buy one and plug the machine you want to use into it.

Call up a good electrical motor repair shop and ask.
A motor meant for 50 Hz will run 6/5 x faster at 60 Hz(typically), but that I think is seldom an issue.
