Rotating electrical machine

摘要

A relay conductor of a rotating electrical machine is provided with: a coil connector that is connected to a coil on one side of a rotating shaft and further to the outside in the radial direction than the coil; a power line connector that is connected to an external power line on the other side of the rotating shaft; and relays that extend in the axial direction of the rotating shaft, and link the coil connector and the power line connector. At least a portion of the power line connector is positioned closer to the inner diameter side of the rotating electrical machine than the outer peripheral surface of a stator.

1. A rotary electric machine comprising:
a stator including a stator core with coils in respective phases wound thereon; a housing that houses the stator therein; a junction conductor electrically joining the coils and external electric power lines, which are disposed outside of the housing, to each other; a rotational shaft formed integrally with a rotor; and same-phase coil joints electrically connecting coil ends of the coils in same phases, on one side in a direction of the rotational shaft with respect to the stator core; the junction conductor further comprising: coil-side joints connected to the same-phase coil joints on the one side in the direction of the rotational shaft with respect to the stator core and radially outward of the coils; electric power line joints connected to the external electric power lines on another side in the direction of the rotational shaft with respect to the stator core; and a junction extending from the one side to the other side in the direction of the rotational shaft over the entire stator core and coupling the coil-side joints and the electric power line joints to each other, wherein at least a portion of the electric power line joints is positioned radially inward of an outer circumferential surface of the stator with respect to the rotary electric machine.
