Abstract

Official abstract text for this publication.

A stator for a rotary electric machine includes a stator core, three-phase coils, and a neutral point connection conductor. The three-phase coils are wound around the stator core. The neutral point connection conductor is connected to each of the three-phase coils. The neutral point connection conductor includes a linear conductor that is bent. The linear conductor includes two end portions and an overlapping portion in which the conductor is folded back and doubled up. One of the two end portions is connected to one-phase coil of the three-phase coils. The other of the two end portions is connected to another-phase coil of the three-phase coils. The overlapping portion is connected to the remaining-phase coil of the three-phase coils.

First claim

Opening claim text (preview).

1 . A stator for a rotary electric machine, the stator comprising: a stator core; three-phase coils that are wound around the stator core; and a neutral point connection conductor that is connected to each of the three-phase coils, the neutral point connection conductor including a linear conductor that is bent, the linear conductor including two end portions and an overlapping portion in which the conductor is folded back and doubled up, one of the two end portions being connected to one-phase coil of the three-phase coils, the other of the two end portions being connected to another-phase coil of the three-phase coils, and the overlapping portion being connected to the remaining-phase coil of the three-phase coils, wherein an end portion of the overlapping portion in an axial direction of the stator includes a bent portion resulting from the conductor being folded back, the bent portion being positioned farther in the axial direction of the stator than the two end portions of the linear conductor. 2 . (canceled)
