Abstract :
Sparking under the brushes of commutating machinery has been investigated in considerable detail, for the purpose of studying and analyzing the various factors which cause sparking. Among the conclusions reached are that in a detailed consideration of sparking phenomena both current density and rate of change of current density must be taken into account.
