Abstract

PURPOSE:To prevent the deterioration of the commutating characteristics of a rotary electric machine by forming recesses for collecting brush powder separately from slits for isolating commutator segments on the outer peripheral edge of a flat commutator, thereby preventing the shortcircuit between commutator segments due to accumulation and growth of the brush powder. CONSTITUTION:Recesses 6D for collecting brush powder are formed on the outer peripeheral side ends of slits 6C of a flat commutator 6 which is composed of commutator segments 6A, radial slits 6C for isolating the segments and insulators 6B of the outer periphery, separately from the slits 6C. The recesses 6D for collecting the brush powder may be formed on the insulators 6B of the outer periphery, or may be formed on the inner periphery of the core 1a to be mounted with the commutator 6.
