Patent ID: 8232691

Claim:
A stator, comprising: a substantially cylindrical stator core that has a fixing ridge provided with a fastening portion for fixing, and is positioned so that an axial center of the stator extends substantially horizontally, wherein the fixing ridge is formed at a circumferential location of a cylindrical main body portion of the stator core, and protrudes radially outward from a main body outer peripheral surface that is an outer peripheral surface of the main body portion, along an entire axial length of the main body portion, and the fixing ridge satisfies the following conditions is a target ridge: an uppermost part of a ridge outer peripheral surface that is an outer peripheral surface of the fixing ridge, 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, and the uppermost part of the ridge outer peripheral surface does not correspond to a boundary with the main body outer peripheral surface, the stator further comprising: sealing members that are respectively attached to both axial ends of the stator core so as to be positioned on a side of the uppermost part of the main body outer peripheral surface with respect to the target ridge, and respectively form sealing walls that have a height equal to or higher than a horizontal plane extending in the uppermost part of the ridge outer peripheral surface, wherein a recess surrounded by the ridge outer peripheral surface, the main body outer peripheral surface, and the sealing walls serves as a refrigerant reservoir recess for storing a refrigerant.
