Subject: [Q] Rocky with same voltage but 50Hz vs. 60Hz, does it make any difference?
I am gonna finally buy a brand new Rocky from Australia.
The seller says it has 50Hz spec. and my region has 60Hz standard.

Before confirming my purchase, I would like to make sure if it makes
any difference.

Is the grinding motor inside the Rocky a DC one or an AC one?

(Any engineer will know what I mean.)

Thanks.

Kevin

Then you mean Rocky is using AC motor directly powered by AC line.
Right?

Thanks Jack.

Yes . AC. Typically grinder motors are of the capacitor start type.

It will turn somewhat faster @ 60 hz. but not enough to make any practical
difference in the results.
