PROBLEM TO BE SOLVED: To provide a densely wound connection shape of a flat wire at a lower cost and in a smaller size.SOLUTION: In a stator 1 for a rotary electric machine according to the present invention, three-phase coils, in which a flat wire 10 of approximately rectangular cross-section is densely wound, are arranged on the inner periphery of an approximately cylindrical stator core 2. In the three-phase coils, coils in the same phase are connected in series, and are arranged on the inner periphery of the stator core 2 so as to sandwich a two-phase coil. The three flat wires in which the coils in the same phase are connected are star-connected at a neutral point 30. The neutral point 30 is arranged on the inner periphery side of the stator core. The connection of the coils in the same phase is provided such that a winding-initiation end part 111 and a winding-termination end part 112 extend in the same direction. The winding-initiation end part 111 is provided on the inner periphery side of the coil, and the winding-termination end part is provided on the outer periphery side of the coil. The winding-termination end part 112 of one coil in the same phase and the winding-initiation end part 111 of another coil are connected.SELECTED DRAWING: Figure 1 |
