CONTACTLESS SENSOR OF ANGULAR POSITION WITH A LINEAR ANGULAR DIAPASON IN THE LIMITS OF 360 DEGREES

摘要

FIELD: the invention refers to automobile electronic instrument making and may be used for definition of the angle of opening of the choker, the pressure degree of the accelerator's pedal, the position of the valve of recycling used gases.;SUBSTANCE: the arrangement has a rotor with diametrically magnetized magnet moving relatively to an immovable stator-programmed integral scheme of a double-axis angular encoder with an analog or pulse-width modulation output and an integrated cruciform massif of sensitive Hall's elements. The magnet is rigidly installed in a bushing with grooves for a screwdriver. The bushing is rigidly installed according to the results of leveling of the magnet in the adjusting bushing of the rotor with fulfilled in it an orienting flat or an orienting groove for installing on the shaft. The turning of the magnetic vector of the rotor is calculated according to the signals of the massif of planar Hall's elements sensitive to the perpendicular field of the integral scheme, on the basis of the algorithm CORDIC. The stator and the rotor are isolated from one another due to the inner lid-limiter rigidly fixed on the surface of the rotor.;EFFECT: makes it easier to define the angle of opening of the choker.;4 cl, 1 tbl, 23 dwg
