European 220 volts is generated at 220 volts to ground. One leg to neutral s 220 volts. Voltages in Europe is kinda wierd NOT the way we are used to it in the US. 220 three phase is the same - a wye setup with the midpoint grounded. The generator is setup with all three legs at 220 volts to a midpoint which is at zero volts and at ground potential.
380 volts is not uncommon, 480 is common. 600 volts for an appliance is not uncommon.
Most motors have nine connections with jumpers for their connections.
Sometimes you run into a motor with 12 connections - not uncommon.
