Abstract:
1. A rotary electric machine comprising: a rotor; a stator comprising: a coolant guide placed to cover at least a circumferential outer part of the end portion of the stator coil from radially outside of the end portion and provided with a plurality of holes therethrough, the coolant guide being configured to guide a coolant therealong in a circumferential direction of the end portion of the stator coil while guiding, through the plurality of holes, a part of the coolant as a first coolant to the end portion of the stator coil, wherein the coolant guide is placed a predetermined distance from the end portion of the stator coil to allow the first coolant to flow between the coolant guide and the end portion of the stator coil, so that the first coolant is guided by the coolant guide while a part of the first coolant is in contact with the coolant guide, and a housing in which the stator and the rotor are installed, the housing comprising a coolant supplier configured to supply the coolant to the coolant guide, wherein the coolant supplier comprises: a frame having a first wall and a second wall opposite thereto, the second wall facing the coolant guide, the second wall being formed therethrough with at least first, second, and third outlets, the second outlet being arranged at one side of the first outlet in a direction of the rotation axis, the third outlet being arranged at the other side of the first outlet in the direction of the rotation axis; a coolant container formed in the first wall in which the coolant is supplied, the coolant container having a bottom wall, the bottom wall being formed therethrough with at least first, second, and third inlets, the second inlet being arranged at the other side of the first outlet in the direction of the rotation axis, the third outlet being arranged at the one side of the first outlet in the direction of the rotation axis; and at least first second, and third passages, the first passage being formed such that the first inlet communicates with the first outlet, the second passage being formed such that the second inlet communicates with the second outlet, the third passage being formed to allow the third inlet communicates with the third outlet.
