    摘要： Disclosed is a carbon commutator, comprising a plurality of metal segments each having a through-hole, a plurality of carbon segments each having a projecting portion, which contains a metal, being inserted into the through-hole to be deformed so as to join the carbon segment to the metal segment, and a commutator body on which a plurality of the metal/carbon joined segments are arranged fixedly in a manner to form a substantially circular body.

    摘要： In a commutator of a rotary electric machine, each of commutator segments has a low-resistive layer made of a low-resistive material and a high-resistive layer made of a high-resistive material having a specific resistance higher than that of the low-resistive material. The low-resistive material contains a carbonic material and a binder. The high-resistive material contains a carbonic material, a binder and an inorganic substance such as boron nitride. A mixing ratio of the inorganic material to the high-resistive material is more than 20 wt %. Alternatively, a brush, which makes contact with the commutator segments, can have the high-resistive layer and the low-resistive layer.
