PURPOSE:To simplify the structure of a rotor by drawing a terminal from each segment of a commutator opposite to the commutator surface of the rotor, and connecting to a rotor coil, thereby reducing the thickness of the rotor. CONSTITUTION:A block of a commutator segment 1 is secured with resin 2 to a rotor shaft 3, and a terminal from each segment is projected to B side opposite to the A side of the segment 1 of the commutator. A substrate 5 is soldered at 6 by slightly projecting the terminal. A rotor coil 4 is held at the substrate 5, and rotated by one revolution together with the shaft 3. In this manner, the motor of small size and reduced thickness can be facilitated.
