Regarding the diagram I have just sent, is the motor 3 phase 400hz?

Single phase ("A" phase) motor. The two sets of windings you're looking at are for direction.

However it is supplied from GEN2 AC bus that I believe is three phase, by the way I have not found any three phase to single phase transformer in the corresponding diagram

It's just using "one" phase out of the three. Regardless of the source.

The print doesn't show three wires coming from the breaker..... only one.

Is the number of C/B's the only indicator of number of phases of power supply to any element in the diagram?
