    摘要: A rotation angle measuring apparatus and method are provided for measuring a rotation angle of a moving disk relative to a stationary disk, the moving disk being configured to rotate about an axis and the stationary disk being arranged opposite the moving disk. A magnet is arranged on the moving disk. A first magnetic sensor is arranged on the stationary disk, the first magnetic sensor generating an angle signal under the action of the magnet as the moving disk rotates. An incremental rotation angle of the moving disk is determined on the basis of an output of the receiving region, a period of the static electric field is determined on the basis of an angle signal generated by the first magnetic sensor, and an absolute rotation angle of the moving disk is determined on the basis of the period of the static electric field and the incremental rotation angle.

    摘要: A non-volatile, absolute rotation sensor (10) employs a radial guide (24) and spiral guide (20) rotating with respect to each other to move a marker element (25) continuously along the radial guide so that a distance of the marker element along the radial guide provides an indication of shaft movement over multiple turns. A sensor system (56) senses the distance of the marker element along the radial guide to provide an electric output.

    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.

    摘要: Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Bestimmung der Position (P) eine Körpers (1) mit einem Feinmeßsystem (20) und einem Grobmeßsystem (30). Der Code (32) des Grobmeßsystems (30) wird vom Feinmeßsystem (20) gesteuert ausgelesen. Das Grobmeßsystem (30) enthält eine Grobcodescheibe (31), die vom Feinmeßsystem (20) über ein Untersetzungsgetriebe (40) angetrieben wird. Das Untersetzungsverhältnis 1/U des Untersetzungsgetriebes (40) ist annähernd 1:1. Die Grobcodescheibe (31) weist hintereinander angeordnete Sektoren mit Codewerten (C) auf, welche die absolute Grobposition des Körpers (1) angeben. Gemäß der Erfindung werden nicht aufeinanderfolgende Sektoren der Grobcodescheibe (31) ausgelesen.

    摘要: A positional encoder comprises a moveable member and at least a first and a second sensor. The moveable member is rotatable relative to the first and second sensors, the first sensor being adapted to capture a first component of a current position of the moveable member and to output a first signal corresponding to the first component, the second sensor being adapted to capture a second component of the current position complementary to the first component and to output a second signal corresponding to the second component, wherein the positional encoder further comprises at least a first memory unit holding a plurality of predetermined look-up values, each predetermined look-up value representing a positional value which corresponds to a respective set of at least the first and second signals and being associated with an individual memory address which is formed by concatenating the signals of the respective set, the first memory unit being configured to receive a memory address which is formed by concatenating at least the first and second signals outputted by the first and second sensors, respectively, and to output the predetermined look-up value associated with the received memory address in response.
