Improvements in the method of determining the magnetic fields of nonlinear dc machines are introduced in part I of the paper. A modified, successive line overrelaxation technique to satisfy boundary conditions is developed. A novel block relaxation technique, the additive acceleration of convergence, is explained. The improved method also takes care of relative position changes between field and armature. In part II [8] the improved method is applied to a large dc machine. A new computer flux plotting procedure is developed in part III [9].
