Abstract

L'invention concerne une tôle d'ensemble magnétique de machine électrique tournante (1) dont au moins une encoche (12) présente un perturbateur d'écoulement (2) qui s'étend en saillie depuis un bord (121-124) de ladite encoche (12) afin de pouvoir perturber un flux (F) de fluide caloporteur traversant ladite encoche (12). L'invention concerne aussi un ensemble magnétique (10) comprenant une pluralité de telles tôles d'ensemble magnétique (1) et dont les encoches (12) forment collectivement une pluralité de canaux de refroidissement (4) dudit ensemble magnétique (10). Les perturbateurs d'écoulement (2) s'étendent ainsi dans les canaux de refroidissement (4) afin de perturber l'écoulement du fluide caloporteur, lesdits perturbateurs d'écoulement (2) formant un ou plusieurs obstacles (41) répartis axialement et/ou angulairement dans lesdits canaux de refroidissement (4). Enfin, l'invention concerne aussi une machine électrique tournante (5) comprenant un stator et rotor dont au moins un des deux est formé par un tel ensemble magnétique (10).
