A stopping member located within an air driven rotor and designed to respond to a magnetic field generated within the rotor housing, causing the complete stoppage of the rotor subsequent to its high speed centrifugation. The stopping member is comprised of a ferrous metal element positioned within the rotor for alignment with the poles of a magnet to facilitate sufficient attractive forces between the magnet and the metal element to completely stop the rotative motion of the rotor on a support cushion of air. |
