ABSTRACT:
A rotation detecting device capable of outputting information on the absolute angle using an ABZ phase signal and without extra operation and procedures required, and a bearing assembly having this rotation detecting device incorporated therein are provided. The device includes an absolute angle detecting sensor unit for detecting the rotation angle of a rotating member as an absolute angle and a rotation pulse signal generating section for generating a rotation pulse signal including an index signal corresponding to a zero phase of the absolute angle detecting sensor unit and a pulse signal of a constant interval, based on the absolute angle detected by the absolute angle detecting sensor unit. The rotation pulse signal is outputted in an absolute angle output mode, under which the rotational pulse signal is outputted from a time the index signal is outputted to the current absolute angle.
