As to delta or wye, motors consist of separate coils that can be connected either way. Open up the junction box and see if three coil wires (and only three, and no power leads) are joined together - "wye". Power leads would then go one to a wire on the other end of each coil. Three groups of three wires says "delta". Dual voltages use more coils and wires.
Why does it matter? 'Twere me, I'd toss a small 3-phase on the floor and hook it up to see if the thing flies.
