No.
But it does give an effective upper limit.
Maximum power transfer theorum says you get maximum power when Rload =3D
Rsource. So your peak power occurs at Rload =3D Rwinding
Power =3D V.I =3D  Voc/2  Voc/(2.Rwinding) =3D Voc^2 / (4.Rwinding).

This is the theoretical maximum power given adqeuate flux, available
mechanical drive, no core saturation and a small host of other
assumptions.
