It is described a stator for an electric machine comprising: a hollow main body; a plurality of supporting teeth extending along an inner surface of said main body; a plurality of windings, each one engaged to a respective one of said supporting teeth; a plurality of operating elements, each one interposed between two successive windings; each one of said operating elements being suitable for thermally interacting with at least one of said windings to cool said at least one winding; each one of said operating elements being in electrical contact with a respective winding of competence being part of said plurality of windings, each operating element being configured to be traversed by a current suitable for supplying said winding of competence.

Integrated electric drive with cooling device

A capacitive element is manufactured by using the multilayer printed circuit board technology. The body of the element includes a layer of dielectric material interposed between two layers of conductive material arranged on opposite sides of the layer of dielectric material. Each layer of conductive material is in turn covered, on its free side, with an external covering layer. The material for making the layer of dielectric material is chosen among materials having: &#x2014;a dielectric permeability &#x3b5;&#x3e;1, &#x2014;a dielectric rigidity k&#x3e;100 kV/mm, and &#x2014;a loss figure Df&#x2264;0.002. Furthermore, the dimensions of the layer of dielectric material are greater than the dimensions of the layers of conductive material, so as to limit the edge effects that might cause discharge phenomena and make the capacitive element flexible.
