    • The method of controlling a reversible, polyphase rotary electrical machine called an alternator-starter, for a motor vehicle with a heat engine, the machine being adapted to work either as an electric generator—in an alternator mode—or as an electric motor, in particular for starting the engine, the machine comprising a rotor with at least one excitation winding, a target and sensors, is characterised in that, starting from sensors of the linear type delivering signals of a sinusoidal type after reading of the target, a summation of the signals delivered by the sensors is performed in a processing unit, by applying a coefficient to the sensors to create signals which are out of phase with each other, and the number of which is equal to the number of sensors, and in that, for each out of phase signal, the sum of the coefficients is zero.

    • 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.
    • 公开了选择产生用于确定旋转机器中的角位置的正弦信号的磁性装置的最佳特性。 该装置包括可绕轴旋转的多极磁环,并根据旋转角度产生可变磁场。 在磁环附近,将磁传感器置于该磁场中,并产生正弦信号。 传感器和环之间的空气间隙是通过将传感器与径向平面上的磁环距离E隔开来构成的。 当多极磁环的厚度e相对于气隙E的径向方向的第一比例e / E为0.4至2.3时,实现最佳性能。 在相对于厚度e轴向的方向上,环的高度h的第二比率h / e在1.5和8之间。
