Abstract : Improvements in the method of determining by numerical methods the magnetic fields of nonlinear dc generators used by the Navy are finalized in a comprehensive computer program. A modified, successive line overrelaxation numerical method is explained, a novel block acceleration of convergence introduced. Position changes between armature and field are considered as preparation for commutation studies. The procedure is applied to find the performance of a 500 hp, 75oV, 4-pole, 300/900 rpm dc machine. The convergence of the relaxation procedure is studied and suitable overrelaxation factors experimentally established. A separate computer program controls a Calcomp X-Y plotter to represent the results with the aid of equi-potential field lines. (Author)
