A rotary electric machine unit includes: a rotary electric machine; and a case that accommodates the rotary electric machine. The rotary electric machine includes: a stator core; a multi-phase coil that is attached to the stator core; a conductive member holder that collectively holds a conductive member connected to a coil end of the multi-phase coil and is disposed outside the coil end in a radial direction; and a terminal block that is fixed to a fastening surface of the case and electrically connects a terminal portion of a power distribution member with a terminal portion of the conductive member. The terminal block is disposed outside the conductive member holder in the radial direction, and at least a part of the terminal block overlaps the conductive member holder in the radial direction.

Rotary electric machine unit

A stator of a rotary electric machine comprises a stator core, a coil; and a plurality of bus bars. When viewed from a rotational axis direction of the rotary electric machine, the first terminal parts of the plurality of bus bars are arranged next to one another substantially in an upper and lower direction on the outside of the stator core in the radial direction, and the second terminal parts of the plurality of bus bars are arranged next to one another substantially in a horizontal direction above the stator core, and a first terminal part arranged on an uppermost side among the first terminal parts of the plurality of bus bars is arranged to be positioned below an uppermost part of the stator core.

Stator of rotary electric machine

A bus bar unit related to one aspect includes: a first bus bar and a second bus bar. The first bus bar and the second bus bar are arranged side by side in a second direction orthogonal to a first direction as viewed from the first direction. The first bus bar includes, as viewed from the first direction, a first straight line portion, a first inclined portion, and a first bent portion. The second bus bar includes, as viewed from the first direction, a second straight line portion, a second inclined portion, and a second bent portion. In an end surface on a second bus bar side of the first bent portion, a distance between the first bent portion and the second inclined portion is longer than a distance between the first bent portion and the second straight line portion.
