The partial differential equations of the potential and the boundary conditions of fields in highly saturated rotating machines at no-load are developed. These are expressed in finite difference form, and in the numerical solution the potentials and the permeabilities are over-relaxed alternately. The choice of a non-uniform system of meshes, and a method of identifying the numerical operations at the mesh points are given. Companion papers illustrate the application of the method.
