DEFINITION

Classification: 322/65

(under subclass 63) Subject matter wherein the generator is provided with interpole or commutating pole windings.

(1) Note. An interpole or commutating pole is an auxiliary pole member placed between the main pole pieces of a commutating machine. Its exciting winding carries a current proportional to the load current and produces a magnetomotive force which minimizes or eliminates sparking at the brushes.
