Abstract: A dynamic balancing apparatus includes a dynamic balancing assembly and a plurality of damping particles. The dynamic balancing assembly includes at least two structural members separately arranged on a rotating shaft connected to a rotor, wherein each structural member includes at least one recess portion. The plurality of damping particles are introduced into at least one recess portion of each structural member, such that a centroid of each structural member deviates from the axis. Accordingly, each structural member generates inertial force and moment of inertia as rotation of the rotor to offset another inertial force and moment of inertia generated by centroid deviation of the rotor while rotating to achieve dynamic balance. The plurality of damping particles can move in the recess portion as rotation of the rotor to induce friction and collision so as to achieve the effects of vibration reduction and noise reduction.
