Abstract: PURPOSE:To reduce a size and a weight of an armature and improve reliability by setting an outside diameter of a commutator riser part larger than an outside diameter of an armature core part and by improving a space factor of the commutator part. CONSTITUTION:A groove diameter of a commutator riser 7 is set equal to or larger than an inside diameter of a lower coil of an armature coil 5 which is wound in an inside groove of an armature core 4. An outside diameter of the commutator riser 7 is set larger than an outside diameter of the armature core 4. A leas wire 12 of a field coil arranged on an outside periphery over the outside diameter of the commutator riser 7 is drawn out from a circumferential groove part provided on an inside periphery of a yoke to outside. Circumference-axis has the relation of L in axis direction and D2 in circumference direction. L in axis direction is positioned at an inside of an end part of a pole core. A gap G1 is brought into existence between the outside diameter of the commutator riser 7 and a field coil 3. Since the outside diameter of the commutator riser 7 can be set large and an outside diameter of a commutator segment 10 contacting electrically to a brush 8 can be set large too, a high space factor of the commutator part can be obtained.
