Rotation angle sensor

摘要

The rotational angle sensor for measuring the rotational angle of a shaft has two code disks, the first code disk of which is rotationally fixed to the shaft while the second code disk is held between the shaft and the housing by two spring groups. Each code disk is assigned to a sensor. The sensor of the first code disk generates a periodic rotational angle signal while the sensor which is assigned to the second code disk generates a coarse signal (U2) which is different from the first signal and which can be used to ascertain which rotation of n possible rotations the shaft is in, wherein n>1.

1. A rotational angle sensor for measuring the rotational position of a shaft, the sensor comprising: a first sensor and a second sensor, the first sensor and the second sensor located proximate the shaft, the first sensor configured to measure the rotational position of the shaft, and the second sensor configured to measure the position of an object, wherein the object is coupled to the shaft by way of at least one first spring, and wherein the object is further coupled to a body by way of at least one second spring, the object being rotationally fixed relative to the shaft.
