    Abstract: A method to construct an electric machine provided with: a stator having a magnetic core longitudinally crossed by a plurality of stator slots; a stator winding having a series of rigid bars, which are “U”-shaped and are inserted through the stator slots defining an entry side, in which the cusps of the “U”-shaped bars are placed, and an exit side, in which the legs of the “U”-shaped bars are placed; the construction method comprises the steps of electrically connecting the ends of at least two non-adjacent legs to one another by means of a connection bridge, which is made of a flat plate arranged perpendicular to the central axis of rotation and has, for each leg, a corresponding “U”-shaped seat, which is suited to receive the end of the leg.

    Abstract: An electronic device including an electronic switch M1, an electrical pre-charge circuit and a measurement, command and diagnosis module. The main electronic switch M1 has a first electrical terminal D1, a second electrical terminal S1, and a main driving terminal G1. The main electronic switch M1 is adapted to take, based on a driving signal DRV, depending on the command signal CMD and on an enabling signal ENB, a closed condition or an open condition, wherein the first electrical terminal D1 is respectively connected to or disconnected from the second electrical terminal S1. The pre-charge electrical circuit is adapted to carry out, based on the command signal CMD, a pre-charge operation, aimed at equalizing the electric potentials (V1, V2) of the first and second terminals of the device, before the main electronic switch M1 takes a closed condition, upon of a transition from the open condition.

    Abstract: The present invention relates to a solid-state relay including a power semiconductor switch device connected between a first electrical terminal and a second electrical terminal and having a command terminal. An electronic driving block is adapted to generate a command signal applied to the command terminal to switch the at least one semiconductor switch device from a closed/open state to an open/closed state to disconnect/connect the first electrical circuit portion from/to the second portion of the electrical circuit. An electronic block detects a current which crosses the power semiconductor switch device. The electronic detection block includes a first electronic device adapted to generate a first signal indicative of a difference of potential between the first and second terminals generated by the current which crosses a total resistance present between the first and second terminals of the power semiconductor switch device in the closed state. The total resistance comprises the sum of a first resistance associated with the semiconductor switch device in the closed state and of second bonding resistances associated with an electrical connection between one of the conductive terminals and the respective either first or second electrical terminal.
