Let's see...
Two phase system with opposite phase (180 degree phase shift) wire in place of neutral produces sine wave with double voltage so that would fit to 220-240VAC tolerance of most European devices.
In three phase system (120 degree phase shift) voltage between two live wires is live to ground voltage multiplied with square root of 3. (400VAC here in Europe)

RPM of electric motors is dependent from frequency so that could be problem in some cases. Also there could be other problems.
