Abstract: Disclosed is an axial fan (1) rotating in a plane (XY) about an axis (2) having a central hub (3) and a plurality of blades (4), which have a root (5) and a tip (6). The blades (4) are delimited by a concave leading edge (7), whose projection in the fan plane of rotation (XY) is defined by two circular arc segments, and a convex trailing edge (8), whose projection in the fan plane of rotation (XY) is defined by one circular arc segment. The blades (4) are made from sections with aerodynamic profiles relatively extending in the direction of their centre line, providing good flow rate and air pressure relative to the overall dimensions of the fan.

Abstract: An electrical machine includes a casing including a base wall provided with a projection projecting from the base wall towards the inside of the casing. A stator includes a core having a plurality of pole shoes, a plurality of conductors wound on the pole shoes to form a plurality of coils constituting a stator winding. Insulators are interposed between the core and the stator winding. A coil of the winding has an end portion engaged with the projection for heat exchange. The insulators include a housing for a first number of turns of the coil and a second housing for a second number of turns of the coil. The first and second housings are shaped such that a layer of the turns of the end portion abutted against the projection is defined by stretches of the conductors all substantially coplanar with each other.

Abstract: An electric machine comprises an outer casing (2), a rotor and a stator (3) having at least one polar expansion (5) and at least one winding (8) having an annular shape and placed around the polar expansion (5). The casing (2) has a plurality of protrusions (13) each of which holds, by supporting, a corresponding portion (12) of a stator winding (8) to enable heat exchange between the winding (8) and the protrusion (13). Each portion (12) of the winding (8) is electrically insulated from the respective protrusion (13).
