Abstract

An electric machine comprises: an electronic module (1) comprising a printed circuit board (2), at least one conductive track coupled to the printed circuit board (2) and at least partly defining an electric power circuit, a conductive element (7) disposed so as to connect a first track portion of said conductive track and a second track portion of said conductive track to determine the closure of the electric power circuit; the electronic module (1) comprises a first heat-sensitive joint between the conductive element (7) and the first track portion held in place by a heat-sensitive joint and positioned on the side opposite the printed circuit board (2) with respect to the conductive track; the electric machine comprises an elastic element (15) pressed against the conductive element (7) to exert a force (F) on the heat-sensitive joint which is configured to yield to said force (F) if subjected to a temperature higher than a predetermined threshold temperature, and a support (11) which houses the electronic module (2); the electronic module (1) is housed in the support (11) with the conductive track and the conductive element (7) disposed towards the support (11); the elastic element (15) is disposed on the side opposite the conductive track with respect to the support (11) and operates between the conductive element (7) and the support (11) so that the force (F) pushes the conductive element away from the conductive track.
