Im currently choosing a new spindle for my build and i was wondering the difference between a 220v and a 380v spindle.

Obviously one operates at a higher voltage. I know all the spindle motors have 3 phases going into them.

Am i right in saying the 220v is a unit that has say 230v single phase powering the VFD whereas the 380v needs a 415v 3 phase supply here in the UK.

Is there any other differences / benefits?
