THE PRESENT INVENTION PROVIDES A COMPACT, EFFICIENT AND NOISELESS ALTERNATOR FOR AN AUTOMOTIVE VEHICLE WHICH EMPLOYS A DOUBLE-LAYER COIL ARRANGEMENT IN A SLOT FOR ELIMINATING A COIL END INTERFERENCE AS WELL AS IMPROVING A SPACE FACTOR. AN AUTOMOTIVE ALTERNATOR (1) COMPRISES A LUNDEL-TYPE CORE ROTOR (3) WITH (16) POLES, AND A STATOR (2) WITH TOOTHED PORTIONS OF (96) POLES SPACED BY SLOTS. U- SHAPED CONDUCTOR SEGMENTS (33) ARE INSTALLED IN THE SLOTS. ONE PORTION OF THE CONDUCTOR IS ACCOMMODATED IN AN OUTER LAYER PORTION OF A PREDETERMINED SLOT, WHILE THE OTHER PORTION IS ACCOMMODATED IN AN INNER LAYER PORTION OF A SLOT PHASE SHIFTED BY AN ELECTRIC ANGLE OF 1800. IN THIS MANNER, ALL OF THE SLOTS ARE SEPARATED INTO THE INNER AND OUTER LAYERS TO ACCOMMODATE A PLURALITY OF CONDUCTOR SEGMENTS (33) . THESE CONDUCTOR SEGMENTS (33) ARE CONNECTED ONLY AT ONE SIDE OF THE STATOR TO FORM A TOTAL OF TWELVE WAVY WINDING COILS. THESE TWELVE WAVY WINDING COILS ARE DIVIDED INTO THREE GROUPS EACH CONSISTING OF A SERIAL CONNECTION OF TOUR WAVY WINDINGS TO CONSTITUTE ONE PHASE OF A THREE-PHASE STATOR COIL. (FIGURE 1)
