Rotating speed phase analyzer, control method thereof, rotating speed phase analysis system and medium

The invention provides a rotating speed phase analyzer, a control method thereof, a rotating speed phase analysis system and a medium. The rotating speed phase analyzer comprises: a base, and an acceleration sensor and a controller, wherein the acceleration sensor and the controller are arranged on the base; the base is used for being fixed on a rotating part; an acceleration sensor used for collecting acceleration values at multiple moments in the process of rotating along with the rotating component; and a controller electrically connected with the acceleration sensor and used for receiving the acceleration values at the multiple moments, determining the rotating speed and/or phase of the rotating part at at least one moment according to the acceleration values at the multiple moments, and sending the rotating speed and/or phase data of the rotating part at the at least one moment to the first equipment. The rotating speed phase analyzer can determine the instantaneous rotating speed and/or the instantaneou
