Which voltage setting for single phase supply?
Which voltage setting for single phase supply?
(OP)
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.






RE: Which voltage setting for single phase 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.

Definitely check the voltage rating.

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.
