Zusammenfassung:The electric machine comprises a rotor (100) and a stator (200) surrounding the rotor (100). The stator (200) comprises a cylindrical stator core (210) having a laminated structure and slots (213) for a stator winding (211) and a stator frame (220) surrounding the stator core (210). The stator core (210) is attached with fastening brackets (300) by means of fastening means (350) based on a compression joint to the stator frame (220). The stator frame (220) comprises two opposite end constructions (221, 222) and at least one frame plate (223, 223A, 223B, 223C, 223D) located between the end constructions (221, 222). Back beams (212) extending in the axial (X-X) direction of the stator (200) are attached to an outer surface of the stator core (210). Each fastening bracket (300) comprises two perpendicular branches (310, 320), whereby a first branch (310) is attached to the stator frame plate (223, 223A, 223B, 223C, 223D) and a second branch (320) is attached to the back beam (212) by means of fastening means (350) based on a compression joint. The fastening means (350) passes through openings (311) in each branch (310, 320). The openings (311) are dimensioned to allow a small movement of the fastening means (350) in the openings (311) so that the stator core (210) can be centralized in a radial direction (R) and in an axial direction (X-X) in relation to the stator frame (220) before the fastening means (350) are tightened in order to lock the stator core (210) to the stator frame (220). L'invention concerne une machine électrique qui comprend un rotor (100) et un stator (200) entourant le rotor (100). Le stator (200) comprend un noyau de stator cylindrique (210) ayant une structure stratifiée et des fentes (213) pour un enroulement de stator (211) et un bâti de stator (220) entourant le noyau de stator (210). Le noyau de stator (210) est fixé avec des supports de fixation (300) par l'intermédiaire d'un moyen de fixation (350) basé sur un manchon de jonction au bâti de stator (220). Le bâti de stator (220) comprend deux constructions d'extrémité opposée (221, 222) et au moins une plaque de cadre (223, 223A, 223B, 223C, 223D) située entre les constructions d'extrémité (221, 222). Des barres arrière (212) s'étendant dans la direction axiale (X-X) du stator (200) sont fixées à une surface extérieure du noyau de stator (210). Chaque support de fixation (300) comprend deux branches perpendiculaires (310, 320), une première branche (310) étant fixée à la plaque de
