PROBLEM TO BE SOLVED: To facilitate winding formation for a stator coil with a straight-angle conductor wound by a plurality of turns without causing a performance degradation.SOLUTION: A winding formation apparatus for a stator coil 14, having a slot section stored in a slot formed at a stator core 12 and a coil end section projecting from an axial end face of the stator core 12, includes a winding fixture in which a plurality of grooves fitted with straight angle conductors at respective stages of the stator coil 14 in the lamination direction and arranged in a predetermined direction are formed and the straight angle conductors are wound. A portion corresponding to the slot of the winding fixture is formed so that bottom faces of the grooves at the respective stages in the predetermined direction are arranged in the predetermined direction while being dislocated in a first orthogonal direction orthogonal to the predetermined direction, and a portion corresponding to the coil end of the winding fixture is formed so that the bottom faces of the grooves at the respective stages in the predetermined direction are arranged in the predetermined direction in the identical plane without being dislocated in a second orthogonal direction orthogonal to the predetermined direction for a lane change of the straight angle conductor in the lamination direction to be performed. |
