Provided is a stator capable of reducing the possibility that the temperature of a stator core becomes non-uniform in axial and circumferential directions in a stator positioned so that its axial center extends substantially horizontally. In a stator 20, fixing ridges 40 are respectively formed at circumferential locations of a cylindrical main body portion 30 of a stator core 21, and protrude radially outward from a main body outer peripheral surface 31 along an entire axial length of a main body portion 30. Of the fixing ridges 40, a fixing ridge 40 that satisfies the following conditions is selected as a target ridge 41: an uppermost part of a ridge outer peripheral surface 42 is located at the same height as, or lower than a horizontal plane extending in an uppermost part of the main body outer peripheral surface 31, and the uppermost part of the ridge outer peripheral surface 42 does not correspond to a boundary with the main body outer peripheral surface 31. The stator 20 includes sealing members 50, which are respectively attached to both axial ends of the stator core 21, and which respectively form sealing walls 51 that have a height equal to or higher than a horizontal plane extending in the uppermost part of the ridge outer peripheral surface 42. A recess surrounded by the ridge outer peripheral surface 42, the main body outer peripheral surface 31, and the sealing walls 51 serves as a refrigerant reservoir recess for storing a refrigerant. |
