It's been years since I had to think about this, but off the top of my head, that seems correct. The stator in a three-phase induction machine has a rotating magnetic field of constant magnitude. A single-phase machine does not. That's why single-phase machines are not self-starting, and it's why they produce characteristic dynamic vibrations due to the pulsation.
That said, I make no claim that the specific values you're getting are correct. Anyone with access to Simulink and a better memory of the subject material is free to tell me I'm wrong.
