Title (EN) ROTARY ELECTRICAL MACHINE
(FR) MACHINE ELECTRIQUE TOURNANTE
Abstract:
(EN) The invention relates to a rotary electrical machine (1) comprising a stator, said stator comprising a bundle (10) of magnetic sheets (20) made up of at least one first sub-bundle (50) and at least one second sub-bundle (60) adjacent to the first, the sheets of the first and second sub-bundles each comprising at least one fin (100) formed at the periphery of the corresponding sheet, the fins (100) of two consecutive sub-bundles being angularly offset relative to one another, in such a way as to create a disruption of the flow of a cooling fluid between the fins at the transition between the first and second sub-bundles, the machine also comprising a housing (5) at least partially covering the bundle of sheets (10), in particular a sheet-metal housing, the housing including a metal sheet wound around the bundle (10) of magnetic sheets of the stator.
(FR) Machine électrique tournante (1) comportant un stator, ce stator comportant un paquet (10) de tôles magnétiques (20) composé d'au moins un premier sous-paquet (50) et d'au moins un deuxième sous-paquet (60) adjacent au premier, les tôles des premier et deuxième sous-paquets comportant chacune au moins une ailette (100) formée à la périphérie de la tôle correspondante, les ailettes (100) de deux sous-paquets consécutifs étant décalées angulairement l'une par rapport à l'autre, de façon à créer une perturbation de l'écoulement d'un fluide de refroidissement entre les ailettes à la transition entre les premier et deuxième sous-paquet, la machine comportant en outre un carter (5) recouvrant au moins partiellement le paquet de tôles (10), notamment un carter en tôle, le carter comportant une tôle enroulée autour du paquet (10) de tôles magnétiques du stator.
