Which voltage setting for single phase supply?

[Icestation2]

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.

380V would indicate either a three phase machine or a single phase machine designed to run from two lines of a three phase supply. 220V would be a normal single phase line & neutral supply.

The voltages should be 230V and 400V following harmonisation - you might enquire why this machine isn't rated for the harmonised European voltage.

Are you using this machine in a 50Hz part of the world? If you are in the 60Hz world there are a few other things to consider.

My business is located in the UK so that will be 50hz I believe.

Check with the manufacturer that our UK 230V - which is still 240V where I live - will not cause damage to the Italian 220V equipment.

Think VFD. That will make three phase from single phase.

Think Italian electrics + UK electricty supply = magic smoke. {smile]

Definitely check the voltage rating.

I would get a three phase spindle and run it with an appropriate VFD running off single phase power. I would not use a single phase spindle..

With a VFD you can easily vary the spindle speed to keep your chip load at the sweat spot, not to mention, much higher reliability.
