Abstract: An axial fan includes a motor, an impeller and a hub of the impeller for connecting to a shaft of the motor. A bottom wall of the hub has a central portion, and an outer annular portion connected to the central portion by an intermediate portion defined by a plurality of blades arranged radially and angularly distributed about an axis of rotation. The blades are elasto-plastic blades and are able to prevent the impeller from moving axially parallel to the axis, moving radially perpendicular to the and a bending of the impeller with movements normal to the plane in which the mean surface of the impeller itself lies. The blades allow a movement with torsional bending around the axis to allow the damping of the resonance frequencies of the assembly formed by the impeller-shaft-rotor.

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: A rotary electric machine includes an enclosure delimiting an internal space for stator and rotor units. An access hole gives access to the internal space. An internal gasket encircles the access hole adjacent a wall of the enclosure. A closing element is disposed in the internal space, movable towards and away from the wall between a closed configuration compressing the gasket to seal the access hole and an open configuration connecting the internal space with the surrounding atmosphere. An elastic device operates to move the closing element from the open to closed configurations to compress the gasket and seal the access hole. The closing element has a pressure surface facing the access hole and accessible through the access hole via a pin. Pressing the pressure surface causes the closing element to move from the closed configuration to the open configuration.
