    摘要： A load machine for a combustion engine test bench includes at least one eddy-current brake associated with at least one electric drive. The brake includes a toothed ferromagnetic rotor secured to a shaft mounted so that it can rotate through a casing containing at least one induction coil borne by an internal peripheral region of the casing, so as to generate a magnetic field across which the rotor is intended to pass in order to generate eddy currents which brake the rotation of the shaft. The shaft is coupled to the combustion engine to be tested, and the electric drive is a variable-reluctance electric motor.

    摘要： A rotating electric machine whereof the rotor includes a magnetic core provided with radial teeth, uniformly distributed at its periphery, annular magnets arranged on either side of the core axial ends and magnetic end flanges pressing the annular magnets against the core, magnetic bars linking the end flanges together, housed in the spaces between the radial teeth, additional magnets being interposed between each of the bars and at least the side walls of the core radial teeth defining the spaces. The stator includes a magnetic core, excitation coils arranged on either side of the core, a stator coil wound on the core and a magnetic ring in contact with the core and provided with radial rims co-operating with the axial rims of the rotor end flanges to form paths for the return flux.

    摘要： A valve actuator for internal combustion engines, includes at least one electromagnet and a magnetic plate, whose movement controls the displacement of the valve. The parameters of the electromagnet and of the plate are such that at least part of the magnetic circuit formed by the electromagnet and the magnetic plate is in a state of magnetic saturation when the magnetic plate is located in the proximity of the electromagnet. The magnetic circuit is preferably in the state of magnetic nonsaturation when it is located at a distance from the electromagnet. According to one embodiment, the magnetic plate has at least one contracted part intended to be saturated when this plate is located in the proximity of the electromagnet.
