PURPOSE:To reduce the height of a rotor coil formed at the end of a rotor by winding rotor coils on the salient poles of the rotor, and sequentially connecting the ends of the coil with a commutator. CONSTITUTION:An armature 100 has salient poles (a)-(h) projected at an equal interval toward the radially outer peripheral side in the circumferential direction. A commutator 20 has segments (i)-(p), and a brush 50 is lid thereto. After a rotor coil 60 connected at one end with a segment (i) is wound in a plurality of turns on the poles 10a, it is connected with a segment (j) adjacent to the segment (i). Then, the coil 60 is wound in a plurality of turns on the salient pole 10b, and connected with the next segment (k). The coil 60 is sequentially wound on the salient poles 10c-10h while connecting with segments (l)-(p), wound on the salient pole 10h, and then connected at the end with the segment (i) being connected in the earlier stage. |
