Abstract
A flat commutator includes a circular arrangement of sectorial carbon segments made of conductive carbon providing commutating surface of the commutator, metallic segments attached to respective of the carbon segments, and a hub body of synthetic resin. The metallic segments have fixing members encroaching into inner and outer peripheral surfaces of the carbon segments, thereby fixing the carbon segments to the metallic segments. The hub body encloses at least fixed portions of the inner and outer peripheral surfaces of the carbon segments that engage with the fixing members of the metallic segments.
