Abstract
(EN)
A stator according to the present invention is provided with a stator core (6), and a coil wound around the stator core. The coil is provided with: a basic coil segment (22) comprising a pair of first leg sections (31), and a first bridging section (32) disposed on a first end surface (14) side of the stator core; and a bridging coil segment (23) comprising a pair of second leg sections (41), and a second bridging section (42). The second bridging section comprises a pair of shoulder sections (43), and a pair of second rising sections (44). The second bridging section is brought into contact with the first bridging section as a result of the angle of inclination of the second rising sections with respect to the first end surface being larger than the angle of the shoulder sections.
(FR)
La présente invention porte sur un stator, comprenant un noyau de stator (6) et une bobine qui est enroulée autour du noyau de stator. La bobine comprend : un segment de bobine de base (22) comportant une paire de premières sections branches (31) et une première section de liaison (32) disposée sur un côté de première surface d'extrémité (14) du noyau de stator ; et un segment de bobine de liaison (23) comprenant une paire de secondes sections branches (41) et une seconde section de liaison (42). La seconde section de liaison comprend une paire de sections d'épaulement (43) et une paire de secondes sections montantes (44). La seconde section de liaison est mise en contact avec la première section de liaison du fait que l'angle d'inclinaison des secondes sections montantes par rapport à la première surface d'extrémité est plus grand que l'angle des sections d'épaulement.

本発明に係るステータは、ステータコア(6)と、ステータコアに巻回されるコイルと、を備える。コイルは、一対の第一脚部(31)、及び、ステータコアの第一端面(14)側に配された第一渡り部(32)を有する基本コイルセグメント(22)と、一対の第二脚部(41)、及び、第二渡り部(42)を有する渡りコイルセグメント(23)と、を備える。第二渡り部は、一対の肩部(43)、及び、一対の第二立ち上がり部(44)を有する。第一端面に対する第二立ち上がり部の傾斜角度が肩部の角度よりも大きいことで、第二渡り部が第一渡り部に接触する。
