In a snow blower that is a single stage the auger is doing both tasks of bringing in the snow and blowing it out the chute. A two stage has a separate impeller that blows the snow out of the chute.
Single phase is a phase related to the neutral. In Belgium that's 230V. But when you have three phases you can use them in relationship with the other phases, and then the voltage between phases is 400V (230V \$\times\$ \$\sqrt{3}\$). Even at three phase you can use the 230V. You'll have 3 times the power available. That's called a star configuration.
