PURPOSE:To enhance the efficiency of a commutator motor and to enable to manufacture the motor in a mass production by winding many turn conductors in a toroidal shape on an annular member to form an armature coil, forming two or more annular coils as a rotor, thereby effectively utilizing the conductor unit. CONSTITUTION:Many turns conductors are wound in a toroidal shape on an annular member 15 made of a magnetic material to form the primary conductor unit 7a' which contributes to torque generation. Then, the second conductor unit 7b' which contributes to the torque generation is formed by winding many turn conductors in a toroidal shape in opposite direction to the first conductor unit 7a' at the position of the member 15, thereby forming one armature coil 7'-1. A plurality of such armature coils are formed on the member 15 to form a rotor. This rotor is opposed to a stator having a field magnet. |
