Abstract[English]
The present subject matter provides an electrical machine (100) comprising: a stator (111), a rotor (113), a first end cover (114) and a lid (132). The first end cover (114) being thermally connected to said stator (111). The first end cover (114) comprising an outer wall (115), and an end cover annular portion (116). The outer wall (115) is spaced at a first distance from the end cover annular portion (116) and forming a radially enclosed portion. The outer wall is provided one or more ports (122,123) to transfer a coolant to the radially enclosed portion. The radially enclosed portion is covered by a base surface (120) wherein the base surface (120) being thermally connected to said stator (111) and the base surface (120) prevents leakage of said coolant to said stator (111).[French]
L'objet de la présente invention concerne une machine électrique (100) comprenant : un stator (111), un rotor (113), un premier couvercle d'extrémité (114) et un couvercle (132). Le premier couvercle d'extrémité (114) est relié thermiquement audit stator (111). Le premier couvercle d'extrémité (114) comprend une paroi externe (115), et une partie annulaire de couvercle d'extrémité (116). La paroi externe (115) est espacée à une première distance de la partie annulaire de couvercle d'extrémité (116) et forme une partie fermée radialement. La paroi externe est pourvue d'un ou de plusieurs orifices (122, 123) en vue de transférer un fluide de refroidissement à la partie fermée radialement. La partie fermée radialement est recouverte par une surface de base (120), la surface de base (120) étant reliée thermiquement audit stator (111) et la surface de base (120) empêchant une fuite dudit fluide de refroidissement vers ledit stator (111).
