Problems solved by technology
[0006] However, in the stator of the rotating electrical machine of Patent Document 1, both the lead-out line and the neutral point are connected to the front ends of the legs of the segment conductors arranged in the innermost layer in the radial direction of the slot, so the lead-out line and the neutral point The shape of the shape becomes complicated, and there is a problem that the manufacturing cost becomes high
In addition, the total length of the lead wire and the neutral point becomes longer, and there is a problem that the vibration resistance is lowered.
In addition, there is a problem that the manufacturing process when arranging the lead wire and the neutral point on the stator becomes complicated

Embodiment Construction
[0073] Hereinafter, an embodiment of a stator of a rotating electrical machine according to the present invention will be described based on the drawings.
[0074]
[0075] like figure 1 and figure 2 As shown, the stator 10 of the rotating electrical machine according to the present embodiment includes a substantially annular stator core 20 and a coil 30 assembled to the stator core 20 .
[0076] It should be noted that, in this specification and the like, for the sake of simplicity and clarity of description, when referring to the axial direction, radial direction, and circumferential direction, they refer to directions based on the central axis CL of the stator 10 and the stator core 20 . Furthermore, the axially inner side refers to the central side of the stator 10 in the axial direction, and the axially outer side refers to a side away from the center of the stator 10 in the axial direction.
[0077] The stator core 20 has a substantially annular shape, and includes a ...

Provided is a stator for a rotating electrical machine, in which a leading-out line and a neutral point can be configured in a simple shape, the overall length of the leading-out line and the neutral point can be shortened, the vibration resistance can be improved, and the manufacturing process when the leading-out line and the neutral point are disposed in the stator can be simplified. A stator (10) for a rotating electrical machine is provided with: a stator core (20); and a coil (30) comprising a multi-phase winding formed by a plurality of segment conductors (40) inserted into the plurality of slots (22) of the stator core (20). One end of the winding of each phase is electrically connected to the lead wire, and the other end of the winding of each phase is electrically connected to a neutral point (70). The coil (30) has a bridge that electrically connects two tip portions (44) of different segment conductors (40) of the same phase, and the lead-out line and the neutral point (70) are both connected to the tip portion (44) of the leg portion (41) disposed on the outermost layer in the radial direction of the slot (22).
Description
technical field [0001] The present invention relates to a stator of a rotating electric machine, and more particularly to a stator of a rotating electric machine including a coil in which a plurality of segmented conductors are inserted into each slot. Background technique [0002] Conventionally, a stator of a rotating electric machine is known, which includes: a stator core; The winding is composed of a plurality of segmented conductors inserted in a row in a radial direction into each of a plurality of slots formed along the circumferential direction of the stator core. [0003] For example, Patent Document 1 discloses a stator of a rotating electrical machine in which one end of each phase winding is electrically connected to a lead wire, and the other end of each phase winding is electrically connected to a neutral point. [0004] prior art literature [0005] Patent Document 1: Japanese Patent Laid-Open No. 2012-29370 [0006] However, in the stator of the rotating ...
