PROBLEM TO BE SOLVED: To provide a liquid-cooled rotary electric machine which can suppress reduction in pressure loss at an inlet part and an outlet part of an annular channel of a cooling liquid, and improve cooling efficiency by suppressing gas mixed with the cooling liquid from being stagnant in the annular channel.SOLUTION: In a water-cooled motor, a tip of a liquid feeding pipe 9 is connected to a feed-in opening 7 formed on one end part of a partition part 6 extending in the axial direction in an annular channel 4 in which a cooling liquid flows and partitioning the annular channel 4, a tip of a liquid discharging pipe 10 is connected to a feed-out opening 8 formed on the other end part of the partition part 6, base end parts of the liquid feeding pipe 9 and the liquid discharging pipe 10 extend in the tangential direction of the annular channel 4, and the base end parts of the liquid feeding pipe 9 and the liquid discharging pipe 10 extend in the mutually opposite directions with the partition part 6 as a boundary. |
