Title:
STATOR COIL, AXIAL GAP-TYPE ROTATING ELECTRIC MACHINE, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2015/107791
Kind Code:
A1
Abstract:
Stator coils (10a, 10b) each consist of a plurality of rectangular conductor coil pieces (6), the adjacent connection end sections (20a, 20i, 20j, 20n) of which are connected to each other on the outer diameter side of a stator (1). The coil pieces each have: a folded section (20e) folded in a rotation axis direction on the inner diameter side of the stator; inner diameter-side open leg sections (20d, 20f) opened from both sides of the folded section toward the circumferential directions of the rotation axis; linear sections (20c, 20g) each bent from each of the inner diameter-side open leg sections and disposed so as to pass through the stator from the inner diameter side to the outer diameter side; and an outer diameter-side open leg sections (20b, 20h) opened from the linear sections toward the circumferential directions of the rotation axis and extending to the connection end sections. The inner diameter-side open leg sections extending to the folded section have a correction section (20k) for correcting the position of the rectangular conductor and are formed so as to align the connection end section extending to the correction section with the connection end section of the adjacent coil piece.
