Abstract: An apparatus and a method for managing the energy supplied to a low-voltage system of a motor vehicle that comprises an energy-recovery stage. The low-voltage system, operating at a first voltage, comprises a battery, a system for charging the battery, and motor-vehicle loads supplied by the battery and/or by the alternator. A high-voltage system operates at a second voltage higher than the first voltage. The high-voltage system includes the vehicle energy-recovery stage, which supplies the second voltage. The second voltage is supplied through an intermediate energy-storage system and a DC-DC converter, which converts the second voltage into the first voltage on the low-voltage bus. A module regulates the alternator, that activates at least one first operating mode in which the alternator regulates a voltage of the battery at a nominal operating value.

Abstract: Exhaust gas recirculation valve actuator device in an internal combustion engine, comprising an actuator body housing where the stem of an exhaust gas recirculation valve, extends along an axial direction. A motor acts to move the recirculation valve along the axial direction X-X, to pass from an open configuration to a closed configuration. A transmission is interposed between the motor and the exhaust gas recirculation valve. The device also includes support and guide mechanism and a sealing mechanism, in correspondence of a connection interface of the actuator body with an associable valve body, which houses an exhaust gas passage duct, wherein the actuator body is mechanically separable/connectable from/to said associable valve body.

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.
