Title
(EN) ELECTRICAL MACHINE HAVING A SEGMENTED STATOR OR ROTOR
(FR) MACHINE ÉLECTRIQUE À STATOR OU ROTOR SEGMENTÉ
Abstract
(EN) A stator (11) or rotor for an electrical machine (10) including a plurality of segments (100), the plurality of segments (100) being circumferentially joined at their ends (23) in such a way that a segment circumferential gap (110) is interposed between two circumferentially adjacent segments (100), the stator (11) or rotor including at least one spacing element (120, 141) provided between two circumferentially adjacent segments (100) for preventing the coil windings (30) of two circumferentially adjacent segments (100) from contacting each other.
(FR) Stator (11) ou rotor pour une machine électrique (10) comprenant une pluralité de segments (100), la pluralité de segments (100) étant joints de manière circonférentielle à leurs extrémités (23) de telle sorte qu'un espace circonférentiel de segment (110) est interposé entre deux segments circonférentiellement adjacents (100), le stator (11) ou le rotor comprenant au moins un élément d'espacement (120, 141) disposé entre deux segments circonférentiellement adjacents (100) pour empêcher les enroulements de bobine (30) de deux segments circonférentiellement adjacents (100) d'entrer en contact l'un avec l'autre.
