relationship between mutual three-phase generators and single-phase generators

I am modeling a single-phase synchronous generator, using data from a three-phase machine, that is, each winding of the three-phase machine would correspond to a single-phase machine, but I am having difficulty finding a relationship between the mutuals. Is it possible to make this relationship?

Each phase of a three-phase machine can be considered as an equivalent single-phase winding. The mutual inductance between the stator and the rotor in the single-phase equivalent is typically the same as that for one phase of the three-phase machine, assuming the windings are identical and symmetrically distributed. In the three-phase case, mutual inductances between stator phases play a significant role, while in the single-phase case, you only have one stator winding, so you only need the mutual inductance between that stator winding and the rotor. Therefore, you can use the mutual inductance data for one phase from the three-phase machine as the mutual inductance for your single-phase model, provided the physical arrangement and winding turns are the same. Hope this helps.
