An electric machine (4) having a tangential architecture comprising a rotor (8), rotating about an axis of rotation (X-X), a stator (12), coaxial to the rotor (8), the stator (12) comprising a casing (16) which incorporates at least partially the rotor (8), a body (20) which incorporates control means of the electric machine (4), the body (20) being placed outside the stator (12) and parallel to the axis of rotation (X-X) in a position substantially tangent to the casing (16) of the stator (12). Advantageously, the rotor (8) comprises a first and a second cooling fan (24, 28), keyed on respective first and second axial ends (32, 36) of the rotor (8), opposite along the axis of rotation (X-X), the first and second cooling fans (24,28) being configured to generate respectively, with the rotation of the rotor (8), a first and a second flow of cooling air independent of each other, wherein the first flow of cooling air is directed toward the first axial end (32) of the rotor (8), and wherein the second flow of cooling air is directed towards the body (20) so as to cool down the control means.
