Claims

[Scope of utility model registration request]

In a rotating electrical machine in which a stator and a rotor are provided in a container, a disc provided with a light reflecting surface at predetermined intervals in the rotation direction is provided on the rotor, and an optical latent receiver is provided opposite to the first attack surface of the disc. A bidirectional optical cable whose end is provided in the container and one end optically connected to the optical transmitting/receiving end, and the other end of the bidirectional optical cable is optically connected and light is transmitted and reflected from the optical transmitting/receiving end to the light reflecting surface of the disk. A branching device that branches signals based on phase difference, and a branching device that supplies light to this branching device. A rotating electric machine characterized by comprising means for measuring a rotational speed signal or a rotational position signal based on the reflected light signal.
