Abstract

A synchronous rotating apparatus synchronously rotates a plurality of rotary shafts independently driven by corresponding driving devices. The apparatus includes: a mechanical regulating member, arranged on the shafts, for maintaining relative rotating positions of the shafts at a predetermined angular difference; a rotation velocity and phase-detecting member, arranged on each shaft, for detecting rotation velocities of the shafts and phases within a regulated angular difference of the regulating member, and a driving control device for controlling the driving devices of the shafts so as to synchronously rotate the shafts based on a phase difference detected by the detecting member. The apparatus is applied to a fluid rotary apparatus.
