SUPERPOSITION TYPE COMMUTATOR MOTOR WITH UNSUPERPOSED ARMATURE COIL GROUP

摘要

PURPOSE:To obtain strong rotary torque and to enable to inexpensively manufacture in a mass production by winding many turn conductors on an annular member to contribute to torque generation in a toroidal shape, thereby forming a rotor. CONSTITUTION:Armature coils 3'-1, 3'-3, 3'-6 are disposed at an equal interval on an annular member 15 formed of a magnetic material so as not to be superposed to each other, and armature coils 3'-2, 3'-4, 3'-6 are disposed to be superposed to each other by displacing the phase in a circumferential direction so that conductor units 3'-2a, 3'-3b, 3'-4a, 3'-4b, 3'-6a, 3'-6b are not superposed with conductor units 3'-1a, 3'-1b, 3'-3a, 3'-3b, 3'-5a, 3'-5b which contribute to the torque generation of armature coils 3'-1, 3'-3, 3'-6, thereby forming a rotor 2'. This rotor 2' is arranged in opposed manner to a stator having a field magnet.
