  • Method of bonding a member to a support by addition of material, and device for arranging two elements, one on the other
    Patent number: 8952288
    Abstract: A method having a step of heating a mass forming a braze. Before the heating step, the method includes steps of arranging the mass and the member on the support. In particular, it includes a step of positioning the mass on the support and a step of applying a first compressive force on the mass so as to compress said mass against the support, the intensity of the first force increasing up to a predetermined first value chosen so as to flatten the mass. Next, the method includes a step of positioning the member on the flattened mass and a step of applying a second compressive force to the member so as to compress said member against the flattened mass and the support, the intensity of the second force increasing up to a second predefined value, the second predefined value being lower than the first predefined value.

  • Magnetic device for determination of angular position in a multiphase rotary electrical machine
    Patent number: 8952685
    Abstract: Disclosed is the selecting of the optimum characteristics of a magnetic device producing a sinusoidal signal for determination of angular position in a rotary machine. The device includes a multi-polar magnetic ring which is mobile in rotation around an axis, and creates a variable magnetic field according to an angle of rotation. In close proximity to the magnetic ring, a magnetic sensor is placed in this magnetic field, and generates the sinusoidal signal. The air gap between the sensor and ring is constituted by spacing the sensor by a distance E from the magnetic ring on a radial plane. Optimum performance is achieved when a first ratio e/E of a thickness e of the multi-polar magnetic ring in a direction which is radial relative to the air gap E is between 0.4 and 2.3. A second ratio h/e of a height h of the ring, in a direction which is axial relative to the thickness e, is between 1.5 and 8.
