Abstract: An electric machine having a tangential architecture comprising a rotor, rotating about an axis of rotation, a stator, coaxial to the rotor with respect to said axis of rotation, the stator comprising a casing which at least partially incorporates the rotor, a power supply body which incorporates a controller for the actuation, the power supply and the control of the electric machine. The power supply body is located outside the stator and parallel to the axis of rotation in a position substantially tangent to the casing of the stator. The controller includes a power module to power the electric machine. The power module is provided with a main heat sink, suitable to dissipate the thermal power emitted by the power module itself, and the power module is thermally insulated from the remaining controller.

Abstract: An electric motor including a rotor, rotating about an axis of rotation, and a stator, coaxial to the rotor. The stator has a casing. A body incorporates a controller of the electric motor. The body is placed outside the stator and parallel to the axis of rotation in a position substantially tangent to the casing of the stator. The rotor includes a first and second cooling fan, keyed on respective first and second axial ends of the rotor, opposite along the axis of rotation. The first and second cooling fans generate respectively, with the rotation of the rotor, a first and a second flow of cooling air independent of each other. The first flow of cooling air is directed toward the first axial end of the rotor, and the second flow of cooling air is directed towards the body so as to cool down the controller.

Abstract: An electric machine comprising a stator comprising: at least one stator winding elements that extends from a first to a second end, separate from each other, at least one electrical bridge suitable to electrically connect the separate ends of said stator winding element, at least a support and attachment plate made of electrically insulating material which defines at least one seat suitable to house at least partially, and retain in position, the electrical bridge, the seat being provided with attachment means which form at least partially a shaped coupling with the at least one electrical bridge, so as to mechanically lock it in position on the support and attachment plate, said seat allowing the passage of the ends of the stator winding element and the electrical connection between the latter and the electrical bridge, the seat electrically insulating the electrical bridge from other components of the stator.

Abstract: An electric machine comprising a stator including at least one stator winding elements that extends from a first to a second end, separate from each other; at least one electrical bridge suitable to electrically connect the separate ends of said stator winding element; at least a support and attachment plate made of electrically insulating material which defines at least one seat suitable to house at least partially, and retain in position, the electrical bridge. The seat is provided with attachment mechanisms which form at least partially a shaped coupling with the at least one electrical bridge, so as to mechanically lock it in position on the support and attachment plate. The seat allows the passage of the ends of the stator winding element and the electrical connection between the latter and the electrical bridge. The seat electrically insulates the electrical bridge from other components of the stator.
