Title: ELECTRICAL MACHINE
Abstract:
Described is a rotary electric machine comprising an electronic module (6) and a heat sink (7) for dissipating the heat produced by the electronic module (6); the electronic module comprises a printed circuit (10), at least one electronic component (12) having a base (14) positioned on the printed circuit (10), a heat transfer device (17) connected to the printed circuit (10) and to the electronic component (12) for transferring the heat generated by the electronic component (12) to the heat sink (7); the heat transfer device (17) comprises an upper portion (18) extending from the printed circuit board (10) towards the heat sink (7) from the same side of the electronic component (12) and a base portion (19) connected to the upper portion (18) and positioned in the printed circuit (10) at least partly under the electronic component (12) to form, at least partly, a preferential path for the heat generated by the electronic component (12), from the base (14) of the electronic component (12) to the heat sink (7); the electronic component (12) is connected at least partly by its own base (14) to the base portion (19) of the heat transfer device (17).
