Based on a theory presented by Ahamed and Erdélyi [1], a method has been developed to find the magnetic flux densities in the air gaps, armatures, poles, and frames of dc machines, taking full account of nonlinearity caused by saturation. A digital computer program to obtain the no-load characteristics of large compensated dc machines is given and applied in analyzing 500-hp, 4-pole dc motors. Computer results agree well with tests.
