You use a one phase motor because you don''t have three phases. That means using phase-phase voltage on it wouldn''t make sense, you should be using a three phase motor instead. The 120V vs. 240V is not related to phase to phase voltage(or live wire to live wire) as that would be $120sqrt(3)approx 207V$.
