Title (EN) SLOT WEDGES FOR A STATOR OF AN ELECTRICAL GENERATOR
(FR) CALES D'ENCOCHE POUR STATOR D'UN GÉNÉRATEUR ÉLECTRIQUE
Abstract:
(EN) Stator (20) for an electrical generator comprising: - a frame body (21) longitudinally extending along a longitu- dinal axis (Y) and including a stator yoke (22) and a plural- ity of teeth (33) radially protruding from the stator yoke (22) to respective tooth radial ends (38), each tooth extend- ing longitudinally between a first tooth longitudinal end (21a) and a second tooth longitudinal end (21b), - at least a wedges (40a-f). The wedge (40) comprises at least a first portion (41) and a second portion (42a-f), the first portion (41) and the second portion (42a-f) being shaped and dimensioned in such a way that, when the wedge (40) is attached to one of the tooth ra- dial ends (38), the first portion (41) extends longitudinally from one tooth longitudinal end (21a, 22a) and the second portion (42a-f) abuts against said one tooth longitudinal end (21a, 22a).
(FR) La présente invention concerne un stator (20) pour un générateur électrique qui comporte : - un corps de cadre s'étendant longitudinalement le long d'un axe longitudinal (Y) et comprenant une culasse de stator (22) et une pluralité de dents (33) faisant saillie radialement sur la culasse de stator (22) vers des extrémités radiales de dent respectives (38), chaque dent s'étendant longitudinalement entre une première extrémité longitudinale de dent (21a) et une seconde extrémité longitudinale de dent (21b), - au moins une cale (40a-f). La cale (40) comprend au moins une première partie (41) et une seconde partie (42a-f), la première partie (41) et la seconde partie (42a-f) étant formées et dimensionnées de telle sorte que, lorsque la cale (40) est fixée à l'une des extrémités radiales de dent (38), la première partie (41) s'étend longitudinalement à partir d'une extrémité longitudinale de dent (21a, 22a) et la seconde partie (42a-f) vient en butée contre ladite extrémité longitudinale de dent (21a, 22a).
