    Abstract: PROBLEM TO BE SOLVED: To obtain a vehicle AC generator configured to achieve a stator core downsizing by using a stator core that one slot is formed for each electrode and each phase, and suppress output drop in a low-speed rotation region due to a zigzag winding. SOLUTION: A stator winding 22 is constructed by Y connection of an X phase winding 25, a Y phase winding 28 and a Z phase winding 31. The X phase winding 25 is manufactured by connecting in series an X1 winding part 26 and an X2 winding part 27 which have a phase difference of 30 degrees in an electric angle. The X1 winding part 26 is manufactured by full-pitch winding a conductor wire. The X2 winding part 27 is manufactured by winding a conductor wire while alternately repeating 2π/3 short-pitch winding and 4π/3 long-pitch winding. A ratio of the number of windings of the X1 winding part 26 to that of the X2 winding part 27 is 1:2. COPYRIGHT: (C)2013,JPO&INPIT
