PROBLEM TO BE SOLVED: To obtain an electric rotating machine in which the terminal treatment of an armature winding is made simple and whose assembling property is made good by a method, wherein a wiring board for armature-winding connection, in which an electrical conductor for a large current is fixed to an annular insulating board is provided at one side of a stator and the terminal of an armature winding is connected to a power-supply connection line via the electrical conductor. SOLUTION: A wiring board 64 comprises an annular insulating board 72. In addition, it comprises an annular electrical conductor 74 which is bonded and fixed to one face of the board 72. In addition, it comprises three electrical conductors 76, 78, 80, which are bonded to the other face. The annular electrical conductor 74 and the three electrical conductors 76, 78, 80 are bonded and fixed respectively to one side of a stator and to the other side of the stator. The electrical conductors 74, 76, 78, 80 are set, in such a way that the cross-sectional area of the flow passage of a current is ensured sufficiently large and that electrical resistance is set suitable for guiding the large current of an armature winding. In the wiring board 64, nine armature windings are divided into three sets, and every set is star-connected. That is to say, the side of the neutral point of every set is connected to the annular electrical conductor 74, and the side of its non-neutral point is connected respectively to the three electric conductors 76, 78, 80. |
