The electrical machine (G) comprises a rotor (1) and a stator (2), while an air-gap (AP) is between the rotor (1) and the stator (2). The stator (2) comprises a number 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 (OP) of the rotor (1). The electrical machine (G) comprises an air-cooling-arrangement (7), which is arranged and used to circulate a gaseous medium for cooling purposes inside the joint cavity.
