The invention discloses a concentricity adjusting device which comprises a sleeve type base arranged in a center hole of a motor stator; an end cover and the upper end face of the base are fixed; the end cover and the upper end face of the motor stator are fixed through a screw; one end of a core sleeve penetrates through a through hole in the center of the end cover and stretches into in a center cavity of the base; an insulating sleeve is arranged between the core sleeve and the base; a measuring rod stretches into a stepped hole in the core sleeve; the measuring rod and the core sleeve are fixed through a stop pin; and a gasket is arranged between a bulged loop of the core sleeve and the end cover. The concentricity adjusting device employs a high-precision machining technology, and realizes the effect that a component is not in contact with a rotating machine when the component penetrates through a central hole and a magnetic steel base flange hole of the rotating machine; during assembly, the component i
