摘要： In a DC-motor according to the present invention, contact areas of first brushes can be enlarged without enlarging the external diameter of a disk on which a commutator is provided; therefore, the wear resistance of the first brushes can be enhanced while maintaining a good control-response; and at the same time, the axial dimension can be shortened dramatically, so that the DC-motor can be downsized.The first brushes 14 are radially in contact with the commutator 11, and second brushes 15 are axially in contact with slip rings 12 that are formed circumferentially inside the commutator 11.
