Embodiment Construction

[0043] figure 1 A block diagram of a position sensor 100 according to the invention according to a first embodiment is shown schematically. The position sensor 100 has a signal generator 110 for generating a periodic magnetic signal S. FIG. The periodic magnetic signal S can be coupled into at least one measuring loop of a position-measuring device to be described hereinafter and induce a corresponding induction signal therein, the evaluation of which enables position determination of the position sensor 100 .

[0044] Furthermore, the position sensor 100 according to the invention has an electrical energy supply device 120 for supplying the signal generating device 110 with electrical energy. It is thus advantageous to realize an "active" position sensor 100 , ie a position sensor 100 which itself actively generates a periodic magnetic signal S and which can be coupled with a correspondingly large amplitude to one or more of the position measuring devices. in multiple measu...

Abstract

The invention relates to a position sensor (100) for an electronic position measuring device (1000), wherein the position sensor (100) has a signal generating device (110) for generating a periodic magnetic signal (S) and Power supply means (120) for supplying power to said signal generating means (110). The position (x) of the position sensor (100) is determined by the position measuring device (1000).

Description

technical field [0001] The invention relates to a position sensor for an electronic position measuring device. Furthermore, the invention relates to an electronic position measuring device. [0002] Furthermore, the invention relates to an actuation method for such a position sensor and an actuation method for such a position measuring device. Background technique [0003] EP 1 442 273 B1 discloses a sensor device for position measurement which is designed for the use of passive position sensors. Passive position sensors have a resonant circuit which is excited by a transmission signal of a conventional sensor device and whose output signal can be coupled into a receiving coil of a known sensor device. Conventional sensor arrangements have relatively low dynamics and relatively low resolution during position measurement. Contents of the invention [0004] The object of the present invention is to provide an improved position sensor and an improved position measuring dev...
