The analysis of the commutating phenomena in d-c machines is an important problem for machine design and development. However, certain inherent difficulties, such as plural equations, nonlineality and singular point, arise which complicate the solving of commutation equation.In this paper, we deal with methods of analysis of commutating phenomena in d-c machins.First, the linearized differential equation of commutation, which is able to treat the narrowing character of the sparkless zone owing to an increase of the armature current, is proposed.Second, we emphasize improved computational procedure throuth the use of the numerical solution by the use of the eigenvector method. The feature of this method is that eigenvalues, modes of the solution and excitation amplitude can be obtained simultaneously. By these statistics, we can estimate commutation quality in d-c machines. The tested machine is a two-pole separately excited generator with lap windings.
