ABSTRACT:
Known rotational signal generators for generating signals that correspond to the rotational speed and/or the angle of rotation of a rotatable component part may be connected with the rotatable component part, by means of a coupling or the like. This coupling results in higher space requirements and in an expensive assembly of the rotational signal generator. The rotational signal generator according to the invention is equipped with a hollow shaft and can be fitted onto the rotatable component part. For the compensation of misalignments or the like of the rotatable component part, the rotational signal generator is mounted elastically. The rotational signal generator may be used for measuring the rotational speed, for measuring the angle of rotation, for measuring the length and for similar operations in the fields of driving technology, systems construction, automatization technology and the like.
