。[Claims for Utility Model Registration] Fixed to a rotor of a rotating machine in a direction perpendicular to the direction of the rotation axis of the rotor, and as the rotor rotates, light rays in the direction of the rotation axis are transmitted and blocked. a rotating disk that changes at least one of the state and the state of a surrounding magnetic field; a detection means for detecting the absolute rotational position of the rotor without contact based on changes in at least one of the light beam or the magnetic field accompanying rotation of the disk; and the detection means fixed to the stator of the rotating machine. A rotating machine with a position detector, characterized in that the rotary machine is equipped with a signal processing means that is attached to the detector and converts the absolute rotational position detected by the detection means into an absolute rotational position signal and outputs the signal.
