Abstract: A rotary electric machine includes an electronic module and a heat sink for dissipating heat produced by the module. The module includes a printed circuit, an electronic component having a base positioned on the printed circuit, a heat transfer device connected to the printed circuit and to the electronic component for transferring heat generated by the component to the heat sink. The heat transfer device includes an upper portion extending from the printed circuit towards the heat sink from the same side of the component and a base portion connected to the upper portion and positioned in the printed circuit at least partly under the component to form, at least partly, a preferential path for the heat, from the base of the electronic component to the heat sink. The electronic component is connected at least partly by its own base to the base portion of the heat transfer device.

Abstract: An electric machine includes a casing, a cap covering the casing to define an enclosure, a heat sink, a circuit board in the enclosure having a first conductive layer as a top face, a second conductive layer as a bottom face, and vias passing through the circuit board between the top and bottom faces. An electronic component is soldered to the circuit board on the first conductive layer and disposed on top of a first part of the vias. A conductive mass is soldered to the circuit board proximal to the electronic component and disposed on top of a second part of the vias. The conductive mass forms part of the circuit through which a power supply of the electric machine flows and is in electric and heat exchange relationship with the electronic component, while the bottom face is in heat exchange relationship with the heat sink.

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.
