Patent ID: 8362662

Claim:
An electric machine comprising: an outer casing; a stator having at least one polar expansion and at least one winding having an annular shape and fitted around the polar expansion; a rotor; wherein the casing has at least one butting portion to engage with and support a portion of the winding to enable heat exchange between the winding and the butting portion, the portion of the winding being electrically insulated from the butting portion when engaged with the butting portion; a plurality of thrust mechanisms, each active on one of the windings to maintain the winding pressed against the butting portion it is paired with; wherein each thrust mechanism comprises at least one elastic element active between the winding and the polar expansion it surrounds; wherein the winding is wound on the respective polar expansion to form a space between the winding and the polar expansion it surrounds, the elastic element being positioned inside the space.
