<p><P>PROBLEM TO BE SOLVED: To provide an improved arrangement for cooling an electrical machine such as a generator. <P>SOLUTION: The electrical machine (G) includes a rotor (1) and a stator (2), while an air-gap (AG) is formed between the rotor (1) and the stator (2). The stator (2) includes a plurality of stacked laminate-plates (5). The laminate-plates (5) are positioned and fixed by means for structural support and by end-plates (13) in relation to a central-part (IP) of the stator (2) to achieve a certain air-gap (AG). A joint cavity is formed by the end-plates (13), the central-part (IP) of the stator (2), the air-gap (AG) and an internal surface of the rotor (1). The electrical machine (G) has an air-cooling-arrangement (7), which is arranged and used to circulate a gaseous medium for cooling purposes inside the joint cavity. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
