SYSTEM AND METHOD USING ROTATING AIR GAPS TO CONTROL MAGNETIC WHEEL ADHESION

A system and method control magnetic adhesion of a wheel to a surface using rotating air gaps. First and second discs have apertures. The first disc retains magnets in the apertures. When the apertures of the second disc are not align with the magnets, adhesion is increased. When the apertures of the second disc are aligned with the magnets, air gaps block magnetic flux to decrease the adhesion. A method implements the system.
