Abstract:
A vehicle AC generator comprising a rotor, a stator having a stator core and a &Dgr;-connected stator winding disposed opposite said rotor, a rectifier unit connected to said stator winding, and a frame for supporting said rectifier unit, said rotor and said stator, whereinsaid stator winding comprises a plurality of phase-windings disposed in said stator core in a circumferential direction at equal intervals so that each of said phase-windings can generate AC voltage having a different phase from others, a plurality of first connection segments and a plurality of second connection segments, each said phase winding comprises a plurality of U-shaped conductor segments, each of said conductor segments has a turn portion forming a first coil-end group disposed on an end of said stator core and a pair of inclined portions forming a second coil-end group disposed on the other end of said stator core, each pair of said phase-windings that generates AC voltages a 180-degree-electric-angle different from each other is directly connected by one of said first connection segments to add said AC voltages thereby forming a series-connected phase-winding, and said series-connected phase-windings are directly connected by said second connection segments to form said &Dgr;-connected stator winding, whereby, said first and second connection segments are disposed circumferentially spaced apart from each other.
