Abstract: A component of electric motor configured to cool windings mounted therein is described, wherein the component is made of a material formed by an aggregate of granules coated with an electrically insulating layer, wherein the granules are substantially in contact with each other.

Abstract: A component (20; 18; 100) is described for cooling the windings of an electric motor (10) comprising: an outer ring (30), an inner ring (40) concentric to the outer ring, linear segments (50) extending radially from the inner ring towards the outer ring, wherein the rings (30, 40) and the segments (50) are internally hollow and joined together to form a continuous channel inside them capable of carrying a cooling fluid along a path that stats at a ring and passes to the other ring, preferably coming back to the starting ring, the rings (30, 40) and the segments (50) being arranged to delimit pass-through openings (36) able to accommodate and surround the motor windings.

Abstract: An electric motor (MC) is described comprising a rotor (100) rotatable about a rotation axis (X), a stator comprising a circular series of windings for creating a magnetic field through which to rotate the rotor; a support provided with a circular series of seats for housing the windings; an element (40, 50), mounted between a winding and a wall of the respective seat which houses it, configured to conduct heat from the winding towards the outside of the stator in order to dissipate the heat.

Abstract: A suspension and traction system (MC) is described for vehicles equipped with a frame and a propulsive element (R), which by rolling on the ground (T) is adapted to move the vehicle relative to the ground (T). A rotary electric motor (12) operates two rotors (14, 16) independently controllable from one another to supply two epicycloidal mechanisms (20, 30) whose outer ring gears (28, 38) are independently movable to rotate about the respective solar gear (24, 34) and rigidly connected substantially to a same point (P) of the frame.

Abstract: The device has an electrical traction machine (20) suspended to a body of a hybrid or electric motorization vehicle and providing engine torque (CM) applied to rear wheels (3, 4). A mechanical link is provided between the machine and a deformable crossmember (2) to transmit torque effect (CR) with the engine torque to the crossmember for descending the rear wheels with respect to the body of the vehicle and for creating anti-squat effect during acceleration in electric propulsion of the vehicle. The link is provided with a connection shaft (30) connected to two levers (21, 33).

Abstract: A suspension system (20) is described for vehicle with a frame, comprising an element (R, 12) propulsive by rolling on the ground; two units (12a, 12b) adapted to impart a torque to the propulsive element that are controllable independently of one another, where the two units are movable relative to the propulsive element independently from one another and rigidly connectable to the frame at one same point (P). By moving one or each unit relative to the propulsive element the distance between the latter and said point is made to vary.
