Document Type and Number:
WIPO Patent Application WO/2024/075455
Kind Code:
A1
Abstract:
The present invention prevents leakage of a filling resin. A disclosed stator structure (20) comprises: a stator (30) having a stator core (31), an insulator (34), and wound bodies (35); a bottomed cylindrical stator frame (40) that houses the stator (30); and a filling resin that fills a first space between the bottom portion of the stator frame (40) and the stator (30) and a second space between adjacent wound bodies (35). The stator core (31) has at least one first passage (33d) and at least one second passage (33e) provided further toward the inner circumferential side than the first passage (33d). The first passage (33d) opens to each of one end of the stator core (31) in the axial direction and the other end thereof in the axial direction. The second passage (33e) opens to each of one end of the stator core (31) in the axial direction and the other end thereof in the axial direction.
