摘要： In the drive arrangement (1) of a curved roll according to the invention, a direct drive motor (2) is attached to a dead axle (13) of the curved roll at the drive end side end of the roll (5). A rotor of the direct drive motor is attached to a roll pipe at the drive end side end of the roll pipe (14). The bearing of the roll pipe functions also as the bearing of the rotor of the direct drive motor (2), thus no own bearings are needed at the direct drive motor.

摘要： A method for manufacturing the frame (1) of an electric machine (9) in which method a stator (8) is formed. In addition, 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 electric 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.
