Nov 21, 2016 at 0:33	comment	added	user57037		I don't even know where to begin. Can you please provide more information about the motor, and maybe a picture of it? What is the motor in? Does it have a faceplate with information on it? You say it "runs at 30 Hz" but that seems odd since the US is a 60 Hz country. In general, if a motor is rated for 60Hz input and is not listed for 50 Hz operation, there is a chance it could overheat at 50 Hz, unless the voltage is reduced correspondingly. But it depends on the motor type.
Nov 20, 2016 at 20:38	comment	added	Sam		The US power grid is 60Hz, the difference between 50 and 60Hz is not usually a big issue for most motors and transformers (with the exception of mains clocks which would run 1.2 times slower). But as John mentioned you need a step down transformer because your "stepping" from a higher mains voltage down to a lower voltage for the motor, 99% of step-up/step-down supplies have no effect on frequency (because it would cost 10 times as much as it would need way more than just a simple transformer)

Nov 20, 2016 at 19:49	comment	added	John D		You need a step-down transformer to run the motor in Ireland, no? If it's synchronous or an induction machine it will run at a lower speed due to the 50Hz in Ireland vs. 60Hz in the US.
