    摘要： The present invention relates to a magnetic position sensor with field direction measurement and flux collector. The invention proposes to measure two magnetic induction components at one and the same point, harmonizing the amplitude of the two magnetic induction components using flux collectors so as to have a ratio of the amplitudes of these two components close to one. For this purpose, the invention provides a contactless position sensor comprising at least one permanent magnet (1), emitting a magnetic field, at least one detection element (3) sensitive to the direction of the magnetic field, and at least one pair of flux collectors (2a, 2b), the permanent magnet (1) being capable of moving in a direction of displacement and having a direction of magnetization that can be continuously varied according to the direction of displacement. Each flux collector (2a, 2b) has at least one portion, provided with an end (8, 9), extending substantially along the direction of displacement of the magnet (1). The ends (8, 9) of a pair of flux collectors (2a, 2b) define a gap (7) oriented along the direction of displacement of the magnet (1). The detection element (3) is positioned outside said gap (7) and substantially equidistant from the ends (8) and (9).

    摘要： The invention relates to a gear motor including a multiple-phase electric motor formed by a stator portion excited by electric coils and by a rotor having N pairs of poles radially magnetised in alternating directions, the stator portion including two angular sectors alpha-1 and alpha-2 with respective radii R1 and R2 comprising wide teeth and narrow teeth radially extending from an annular crown, characterised in that the wide teeth have a width higher than or equal to twice the width of the narrow teeth, in that the notch width is higher than the width of a narrow tooth, in that the angular sector alpha-1 is lower than 220° and includes all the coils, and in that the ratio R1/R2 ranges from 1.2 to 2.

    摘要： The invention relates to an angular or linear magnetic position sensor that comprises a mobile member including at least one magnet (1) having a magnetisation direction that varies linearly along the movement direction of the magnet in a surface defined by said movement direction and in a normal direction, at least four magneto-sensitive elements (2, 3 and 4, 5) and at least one processing circuit (6) providing a signal based on the absolute position of the mobile member, characterised in that a first set of magneto-sensitive elements (2, 3) and (4, 5) are located at a same point, the first couple of magneto-sensitive elements (2, 3) being spatially offset from a second couple of magneto-sensitive elements (4, 5) along the movement direction, and in that the magneto-sensitive elements (3 and 5) measure the tangential component of the magnetic field while the magneto-sensitive elements (2 and 4) measure the normal component of the magnetic field in order to provide, after algebraic combination of the components taken in pairs, two sinusoidal signals substantially having an electrical phase shift of 90°.

    摘要： The invention relates to an absolute position magnetic sensor for measuring the angular position, on a theta course, of a shaft passing through said sensor and comprising at least two systems for detecting the position of the shaft. Said invention is characterised in that: at least one of the detection systems generates a signal according to a "periodical" function of the theta/n period giving the periodical angular position of said shaft; at least one of the detection systems generates an absolute signal on a theta course of the shaft; and theta and n fit the equation: * theta/n = 360 * n > 1.
