A method for manufacturing the frame (1) of an electric machine (9) in which method a stator (8) is formed. In ad-dition, in the method the first sheath (91) of sheet metal is formed around the stator (8) which sheath is attached to the stator by laser welding, as well as a cooling element (93) is formed which element is attached to the first sheath by laser welding. The elec-tric machine (1), in turn, comprises at least a frame (9), a stator (8) attached to the frame, an axis (6), a rotor (7) attached to the axis and the front flange (3) to which a bearing casing (11) has been fitted in order to fit the bearing (10) used to support the axis. Bearing casing (11) has been fitted into the front flange (3) in such a manner that the bearing (10) can be placed into the bearing casing from inside the frame (9). In addition, the invention relates to the frame of an electric machine.
La présente invention a trait à un procédé de fabrication du cadre (1) dune machine électrique (9) dans lequel un stator (8) est formé. De plus, dans le procédé, la première gaine (91) de tôle est formée autour du stator (8) et est attachée au stator par soudage au laser. De même, un élément de refroidissement (93) est formé, lequel élément est attaché à la première gaine par soudage au laser. La machine électrique (1), à son tour, comprend au moins un cadre (9), un stator (8) attaché au cadre, un axe (6), un rotor (7) attaché à laxe et la bride avant (3) sur laquelle un carter de palier (11) a été ajusté afin dajuster le palier (10) utilisé pour supporter laxe. Le carter de palier (11) a été ajusté dans la bride avant (3) de manière à ce que le palier (10) puisse être placé dans le carter de palier depuis lintérieur du cadre (9). De plus, la présente invention a trait au cadre dune machine électrique.
