# How does using a 60Hz device on a 50Hz supply affect it?

I've two Vibro Graver electric engravers (120V 60Hz) with me. I gave one to a friend who recently moved to another country. He got a step down converter from 220V to 110V but then he noticed the frequency used there is 50Hz.

What would the effects of using the device on a 110V 50Hz supply when the device is meant to be used on 120V 60Hz supply. Does the 10Hz difference cause any damage?

Edit: The voltage is stepped down from 220V 50Hz to 110V 50Hz Img 1

• Likely will go unnoticed...And 120V to 110V stepdown? I doubt it is needed as well. – Eugene Sh. Oct 26 '17 at 20:39
• So, its safe to go ahead? I'm slightly confused because a person told me yesterday that sometimes inductive devices don't like frequency changes much. Is it true? – The_Vintage_Collector Oct 26 '17 at 20:41
• That's true. The question is how "much". Best thing would be to ask the manufacturer. – Eugene Sh. Oct 26 '17 at 20:42
• The adjuster is labelled "stroke" so I would expect it to adjust the amplitude of the vibration rather than the frequency. I suspect @Trevor is right about the 17% slower. – Finbarr Oct 26 '17 at 20:58
• @ThePhoton I agree, but you need a reference to know that it doesn't sound right. For example I have no idea how this thing should sound like :) – Eugene Sh. Oct 26 '17 at 21:29

• @Rahul, is this $90 12v-inverter the better option? Wouldn't be better if he buys an engraver in the country where he's living now? – mguima Oct 28 '17 at 14:20 • @mguima :D Only if it was just the engraver. He seemed to have taken some other appliances/devices too. He already ordered a$200 3000W 115V 60Hz inverter he told me. – The_Vintage_Collector Oct 28 '17 at 16:25
