Voltage Setting for a Single-Phase Power Supply

04/08/2009 7:58 AM

I am buying a high speed spindle from a company in Italy. They have two different voltage options available for the spindle which are either 220 or 380. I operate my CNC router using a single phase power supply. Can anyone confirm which voltage option I should go for.

Single phase voltage will be obviously 220 VOLTS AC. 380 is a three phase voltage

You almost certainly need the 220V version - but where are you located? What's on the rating plate of any other equipment you're running from this supply?

220V. (It should probably be offered as 230V, as Italy (along with the rest of us) have standardized! The 230V spec has wide enough tolerances to include the old UK 240V and the 220V used by some European regions.)

If your workplace accomodates 3-phase supply then i would go for the 380Volt solution, if you have only 220Volt then go for the 220Volt option.

You should let us all know what kind of CNC machine you have...

--->I'm a cnc hobbyist myself<--- I have built a 3foot by 6 foot heavy duty machine for milling metals. I used 1600oz/in stepper motors and geckodrive G202 drivers.

Italy => UK... definitely go for 220v. I assume there would be no 50Hz / 60Hz motor conflicts here.

I asked my neighbor (an electrical contractor) what it would take to have 3 phase installed here. His reply was "How many thousands of $$ are you willing to pay for it?".

So go for 220.
