Abstract: The invention relates to the process and device for adjusting a rotary encoder, i.e. the absolute magnetic rotary encoder with Hall effect sensors which, when positioned in the form of a circle, detect the magnetic field of a diametrically polarised permanent magnet. The rotary encoder adjustment process features the following: the actuator magnet turns once or several times over the sensor circuit, whereby the time-dependant rotation angle is recorded/stored; time-dependant presupposed values of the rotation angle are calculated; these are then subtracted from the measured actual rotation angle values; by analysing the obtained difference, the electric parameter values for the sensor circuit are determined in such a manner as to make the newly measured difference based on new electric parameter values smaller than before the change; the electric parameter values for the sensor circuit are written into the sensor circuit.

Abstract: A magnetic encoder apparatus is presented that includes a plurality of magnetic sensor elements (e.g. Hall sensors) for reading an associated magnetic scale that produces a periodically repeating magnetic pattern. The plurality of magnetic sensor elements produce a plurality of sensor signals and an analyzer is provided for analyzing the plurality of sensor signals to provide a measure of the position of the magnetic sensor elements relative to the associated magnetic scale. The analyzer is arranged to use the plurality of sensor signals to assess the period of the periodically repeating magnetic pattern sensed by the plurality of magnetic sensor elements. In this manner, the requirement to carefully match the period of the sensor elements with the periodically repeating magnetic pattern of the associated magnetic scale is avoided.

Abstract: A magnetic encoder scale (30) comprises a series of periodically spaced magnetic marks. A reference mark (34) is applied to the scale using an applicator or template (32), which has a feature (33) for locating the reference mark. The applicator or template (32) comprises one or more magnetic marks corresponding to the periodic scale marks, whereby the applicator or template automatically assumes a defined phase relationship relative to the periodic scale marks when placed on the scale. The reference mark may be attached to the scale self-adhesively. Or it may be formed by removal of material from the scale, guided by the applicator or template. Or the applicator may comprise a strong permanent magnet which applies further magnetisation to a region of the scale.

Abstract: The present invention relates to the improved magnetic encoder apparatus for measuring the position of a readhead relative to the magnetic scale. The magnetic encoder apparatus according to present invention enables the same precision of determining the position as magnetic encoders with encoded bits into the periods of the magnetic scale, disclosed in the state of the art, but improves on them by overcoming the limitation of the length of the magnetic scale imposed by the number of bits in the word. The magnetic encoder according to this invention enables multiple increase of the (measuring) length of the magnetic scale without increasing the number of the magnetic sensor elements on the readhead per track and related number of periods of the magnetic scale that the plurality of the magnetic sensor elements on the readhead extends across. Furthermore, it is possible to increase the (measuring) length of the magnetic scale without changing the length of the period on the magnetic track.

Abstract: Magnetic encoder apparatus (2) is described that comprises a plurality of magnetic sensor elements (e.g. Hall sensors) for reading an associated magnetic scale (4; 10) that produces a periodically repeating magnetic pattern. The plurality of magnetic sensor elements produce a plurality of sensor signals and an analyser (7) is provided for analysing the plurality of sensor signals to provide a measure of the position of the magnetic sensor elements relative to the associated magnetic scale (4; 10). The analyser (7) is arranged to use the plurality of sensor signals to assess the period (60) of the periodically repeating magnetic pattern sensed by the plurality of magnetic sensor elements.

Abstract: The body for separating the rotational and linear motion solves the problem of separating the rotational and linear motion of the guide shaft (3). According to the invention, the body includes a guide shaft (3), a static part (2) of the body and a rotary part (1) of the body. The movement of the guide shaft (3) relating to the static part (2) is enabled by the first supports (7). The transmission of the rotation of the guide shaft (3) is ensured with the rotation transmission attachment (12), which is attached to the guide shaft (3). With the help of second supports (13) inside the rotation transmission attachment (12) for transmitting rotation, and one or more guides (11), the rotation transmission attachment (12) transfers rotation to the rotary part (1) of the body, which is, via a connecting element (10) with one or more third supports (14), separated from the static part (2) of the body. The rotation of the guide shaft (3) is transmitted via the rotation transmission attachment (12) to the rotary part (1) of the body, using the guides (11) and the connecting element (10) to which the guides (11) are fixed. The device for simultaneously measuring rotary and linear movement of the guide shaft (3) includes said body and position encoders, which are mounted on the body. The body further includes an encoder readhead (9) for measuring rotation and an encoder readhead (8) for measuring linear movement, both mounted in the static part (2) of the body, an encoder scale (B) mounted in the rotary part (1) of the body for measuring rotation, and an encoder scale (D) integrated in the guide shaft (3) for measuring the linear movement.

The readhead includes a plurality of sensors, such as an array of Hall sensors (30;82), for producing a plurality of sensor signals (H). A plurality of signal combiners (84) are also provided to receive at least two of the sensor signals and produce therefrom a combined sensor signal (S). A plurality of data bit extractors (86) are arranged to receive at least two combined sensor signals (S) and to determine the value of a data bit encoded in an associated absolute scale (4;40;50;80). The readhead (6;76) also comprises an incremental signal generator (88,90) for generating at least one incremental signal (Sin/Cos) from the combined sensor signals (S) produced by a plurality of the signal combiners (84). In this manner, both absolute and incremental position is measured.
