Abstract: According to one embodiment, a stator includes a stator core with slots, and multi-phase segment coils each including coil segments each including a first linear part and a second linear part arranged in different slots and a bridge part, the coil segment formed of a rectangular conductor. An innermost coil segment in the slot is structured with divided segments adhered together. Each divided segment includes a first linear part and a second linear part, and a bridge part, and is formed of a rectangular conductor cross-sectional area of which is smaller than the rectangular conductor of other coil segments. The bridge parts of the divided segments are arranged to cross each other in the radial direction.

Abstract: A stator for a rotary electric machine of an embodiment includes: a dividing core including a yoke portion and a teeth portion protruding in an inner peripheral direction from the yoke portion; bobbins that are made of an insulating material and are arranged on both ends in an axial direction of the dividing core; a coil that is wound around the bobbin; and insulating papers that are arranged along an inner peripheral surface of the yoke portion and a side surface of the teeth portion and insulate the coil and the dividing core from each other between both the bobbins, and each of the bobbins is formed with a groove into which an axial end of the insulating paper is inserted, and the groove is configured such that a width dimension of a part along the inner peripheral surface of the yoke portion is larger than a width dimension of a part along the side surface of the teeth portion.

Abstract: According to one embodiment, in a method, while supporting as end of an extension part of a coil segment by a flange of a forming jig from the radially outside and pressing an inclined, surface toward the other end surface in an axial direction of the stator core by a pressing part of the forming jig, rotating the stator core in a circumferential direction relative to the forming jig, in order to bend the extension part in the circumferential direction of the stator core such that the inclined surface is positioned to be substantially parallel to the other end surface. Thereafter, joining the inclined surfaces adjacent to each other is the radial direction of the stator core.

Abstract: According to one embodiment, each of a pair of straight sections of a coil segment is inserted into a slot of a stator core from a first end face side of the stator core, extension end sections of the straight sections are made to protrude from a second end face side of the stator core. A jig is arranged on the second end face side of the stator core in a state where each of extension end section hold sections of the coil segment is held by the jig, the position of the jig relative to the stator core is turned in a circumferential direction, a bend section positioned between the stator core and the jig is bent in the circumferential direction, and the whole of the extension end section hold section is cut off.

Abstract: A rotating electric machine of one embodiment includes a stator provided with a stator core having windings of each pole of each phase lap wound thereto; and a rotor provided rotatably with respect to the stator. The stator core is provided with slots each having two or more parallelly connected windings of equal turns count inserted therein.
