Title (EN) SYSTEM FOR DETERMINING AT LEAST ONE ROTATION PARAMETER OF A ROTATING MEMBER
(FR) SYSTÈME DE DÉTERMINATION D'AU MOINS UN PARAMÈTRE DE ROTATION D'UN ORGANE TOURNANT
Abstract: front page image
(EN)The invention relates to a system comprising: a coder (1) whose magnetic track (2) exhibits an alternation of North and South magnetic poles separated by i Archimedean spiral transitions (3); a rotation sensor able to detect the periodic magnetic field emitted by said coder by means of several sensitive elements (4), the sensitive elements (4) being distributed angularly along the magnetic track (2) while forming between at least two sensitive elements (4) an angle α which is designed so that the signals delivered by said elements are in quadrature.
(FR)L'invention concerne un système comprenant : un codeur (1) dont la piste magnétique (2) présente une alternance de pôles magnétiques Nord et Sud séparés par i transitions (3) en spirale d'Archimède; un capteur de rotation apte à détecter le champ magnétique périodique émis par ledit codeur au moyen de plusieurs éléments sensibles (4), les éléments sensibles (4) étant répartis angulairement le long de la piste magnétique (2) en formant entre au moins deux éléments sensibles (4) un angle α qui est agencé pour que les signaux délivrés par lesdits éléments soient en quadrature.
