Abstract: A method for controlling an electric ventilator includes: setting a first threshold temperature T1D of a microcontroller lower than a maximum threshold temperature T3D of the microcontroller; monitoring a temperature TD of the microcontroller; setting a first threshold temperature T1M of an electronic power device lower than a maximum threshold temperature T3M of the electronic power device; monitoring a temperature TM of the electronic power device; preparing a counter of a predetermined time X; activating the counter if the temperature TD or the temperature TM exceeds respective first threshold temperatures T1D, T1M; reducing a speed V of rotation of an electric motor to a second value V1 lower than a first value V1 if after the predetermined time X, the temperature TD or the temperature TM is higher than the respective first threshold temperatures T1D, T1M.

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 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.
