Abstract
To provide a rotary electrical machine having a novel configuration adapted to provide axial downsizing of the rotary electrical machine when connecting an electrical connection conductor to a welded side terminal section of a coil end of a segment coil. The rotary electrical machine includes: a stator coreincluding slots radially extended in a radial fashion; a plurality of segment coilsradially stacked and accommodated in the slot; and a neutral point bus-barlaid on a side of a welded coil end of the segment coiland including a connection wiring section and a connection section for interconnecting the different segment coils. In a state where the segment coilsare mounted, at least a part of the connection wiring section is laid in a radial space RS radially defined by the segment coils. The connection wiring section can be laid in the radial space RS radially defined by the segment coilsso that axial elongation of a configuration space for the electrical connection conductoris prevented. Thus, the axial downsizing of the rotary electrical machine can be achieved.
