Title:
STATOR, ELECTRIC MOTOR, AND VENT FAN
Document Type and Number:
WIPO Patent Application WO/2019/058486
Kind Code:
A1
Abstract:
A stator (1) is provided with a stator core (5), a winding frame (11) around which a winding (12) is wound, and an insulating body (33). The stator core (5) includes a yoke (21) that is an external core and a plurality of tooth portions (22) forming an internal core surrounded by the external core. The winding frame (11) covers the internal core. The insulating body (33) is disposed between the winding (12) and the external core. The winding frame (11) is provided with a guide portion (31) for guiding insertion of the insulating body (33) between the winding (12) and the external core. The stator (1) can reduce positional error of the insulating body (33), thereby ensuring stable insulation between the stator core (5) and the winding (12).
