Abstract:
This dynamo-electric machine can be cooled by causing a refrigerant to flow along the outer periphery thereof, and comprises: a stator; a housing, which is a cylindrical member for housing the stator in the inner circumference thereof, and which has a flow passage groove formed so as to be recessed in the circumferential direction in the outer circumference thereof, and an annular first protrusion and an annular second protrusion, which face each other in the axial direction on the outer circumference with the flow passage groove interposed therebetween, and which protrude in the radial direction; a cover that covers the outer circumference of the housing, and contacts the first protrusion and the second protrusion; and a partition plate that partitions the flow passage groove in the axial direction with one end disposed at a first notch provided in the first protrusion, and another end disposed at a second notch provided in the second protrusion. The width in the circumferential direction of the first notch is wider than that of the second notch. The partition plate has one end formed with substantially the same width as that of the first notch, and another end formed with substantially the same width as that of the second notch.
