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.
