| titleOfInvention | Rotating electric machine and manufacturing method thereof |
| abstract | A rotating electrical machine capable of achieving both output performance and ensuring brush life is provided at low cost. A commutator 5 is configured by arranging a plurality of segments 8 molded on an insulating member 7 in a cylindrical shape, and is assembled by fitting the insulating member 7 on one end of the armature shaft by press-fitting or the like. It is done. The segment 8 is provided with a low resistance layer 8a and a high resistance layer 8b having different electrical resistances on the commutator surface on which the brush slides. In the low resistance layer 8a and the high resistance layer 8b, for example, the low resistance layer 8a has a higher copper content than the high resistance layer 8b, and the low resistance layer 8a has a lower electrical resistance than the high resistance layer 8b. It is configured like this. The low resistance layer 8a and the high resistance layer 8b are provided on the both ends of the commutator surface, that is, on the front end side and the rear end side of the segment 8 forming the commutator surface with respect to the rotation direction of the commutator 5. 8b is disposed, and the low resistance layer 8a is disposed between the two high resistance layers 8b.
