ABSTRACT:
A rotary machine having a rotating detection mechanism for detecting rotational speeds as a frequency signal is disclosed. The rotary machine comprises a rotary machine body, a disk shaped magnet tightly fitted onto a rotating shaft projected from the body, a ring shaped coil unit loosely mounted around the disk magnet for generating a frequency output corresponding to rotational speeds of the body, and a ring shaped member supporting the ring coil unit around the disk magnet.
