Abstract

PURPOSE:To conduct electricity in the both directions of armature coils by means of a simple circuit by a method wherein the changes of the resistance value of a photoconductive films are utilized, and currents from a power source are fed to the armature coils through a commutator in noncontact shapes. CONSTITUTION:When forming a motor as an outer rotor type DC motor, a yoke 11, on an inner circumferential surface thereof a cylindrical magnet 12 is fixed, and a disc 16 with slits 18, 19 are mounted to a shaft 10 and integrally rotated, and a core 13 with three-phase armature coils 14a-14c and a commutator 15 are installed at the stator side. Here, the commutator 15 is formed by each arranging conductive films 23, 27 connected to a power source, photoconductive films 24, 26 and commutator bars 25a-25c mutually insulated and each connected to the armature coils 14a-14c on an upper surface of an insulating substrate 21 according to a fixed method. Light from a lamp 20 is irradiated to the photoconductive films 26, 24 of the commutator 15 through the slits 18, 19 of a disc 16, the resistance value of the irradiated sections of the photoconductive films 24, 27 is lowered, and a fixed armature coil is conducted.
