Title:
STATOR STRUCTURE AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/026733
Kind Code:
A1
Abstract:
The present invention prevents a leak of a filling resin. This stator structure (20) comprises: a stator (30); a stator frame (40) which has an opening (40a) and accommodates the stator (30); and a filling resin (70). The stator (30) has a stator magnetic core (31) including a plurality of tooth sections; insulators (33) covering the respective tooth sections; and a winding body (34) wound onto the insulators (33). The filling resin (70) fills a first space (S1) between the bottom (40b) of the stator frame (40) and the stator (30), a second space between an inner circumferential surface (40s) of the stator frame (40) and an outer circumferential surface (31s) of the stator magnetic core (31), and a third space between the mutually adjacent portions of winding body (34). The stator frame (40) has a resin injection path (41). The resin injection path (41) includes: an injection port (41a) open in the vicinity of the opening (40a); and a dispensing port (41b) open in the first space (S1).
