Title:
STATOR STRUCTURE AND BRUSHLESS MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/035400
Kind Code:
A1
Abstract:
A stator structure (1) according to an embodiment is provided with: a stator core (10); a first insulator (20) and a second insulator (30); a plurality of coils; and a plurality of pins (40). The stator core (10) is configured by laminating thin band-like magnetic materials (10a) and has a plurality of teeth (12) extending radially from an annular main body part (11). The first insulator (20) and the second insulator (30) are made of resins and cover both sides of the stator core (10) in the axial direction. Each of the plurality of coils is wound on an extension part (12a) of the plurality of teeth (12) through the first insulator (20) and the second insulator (30). The plurality of pins (40) are formed integrally with at least one among the first insulator (20) and the second insulator (30), and couple the first insulator (20) and the second insulator (30).
