A system and method control magnetic adhesion of a wheel to a ferromagnetic surface using sliding magnets, which slide in and out of a disc. Moving the magnets into the apertures generates a magnetic flux, increasing the magnetic adhesion. The system implements the method.

System and method using sliding magnets to control magnetic wheel adhesion

A system and method control magnetic adhesion of a wheel to a surface using internal short-circuit conductors. The method includes providing the wheel having a first disc, apertures retaining magnets, and a conducting ring, and a second disc. In a first configuration, the second disc is isolated from the conducting ring to generate a first magnetic flux to increase adhesion. In a second configuration, magnetic interaction of the second disc and the conducting ring generates a second magnetic flux to decrease adhesion. The system implements the method.

System and method using internal short-circuit conductors to control magnetic wheel adhesion

An actuation system and method are actuated to control magnetic adhesion of a wheel to a surface. The actuation system is coupled to the wheel having inner and outer annular discs and the wheel is configured to adhere magnetically to a surface. The actuation system has a motor configured to rotate a first disc and to not rotate a second disc. In a first configuration, the motor rotates the first disc relative to the second disc in a first rotational direction, thereby generating a first magnetic flux to increase the adhesion of the wheel to the metallic surface. In a second configuration, the motor rotates the first disc relative to the second disc in a second rotational direction opposite the first rotational direction, thereby generating a second magnetic flux to decrease the adhesion of the wheel to the metallic surface. A method is also disclosed.

System and method for actuation to control magnetic wheel adhesion

A system and method use a magnetic cancellation loop to control magnetic wheel adhesion. The wheel has an inner annular disc composed of a non-magnetic material with apertures to retain ferromagnetic structures and magnets, and an outer annular discs composed of a ferromagnetic material and are disposed on either side of the inner annular disc. Each outer annular disc has a non-magnetic isolator ring having curves extending in a serpentine manner. In a first configuration, the curves isolate the ferromagnetic structures from the magnets, thereby generating a first magnetic flux to increase the adhesion of the wheel to the ferromagnetic surface. In a second configuration, at least one outer annular disc is rotated to dispose the curves to allow magnetic interaction between the ferromagnetic structures and magnets, thereby generating a second magnetic to decrease the adhesion of the wheel to the ferromagnetic surface. The method implements the system.

System and method using a magnetic cancellation loop 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.

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 internal cancellation magnets. An inner annular disc of the wheel comprises a non-magnetic material and has first and second apertures which retain magnets while an outer annular disc comprises a ferromagnetic material and is disposed on a side of the inner annular disc and has a non-magnetic isolator ring which extends in a serpentine manner. In one configuration, the curves of the serpentine isolator ring isolate the first magnets from the second magnets. In another configuration, the outer annular disc rotates relative to the inner annular disc to dispose the curves of the serpentine isolator ring in a second position to allow magnetic interaction between the first and second magnets to generate a second magnetic flux between the second magnets and the ferromagnetic surface to thereby decrease the adhesion of the wheel to the ferromagnetic surface.

System and method using internal cancellation magnets to control magnetic wheel adhesion

An arrangement of cancellation electromagnets control magnetic adhesion of a wheel to a surface. The wheel has an inner annular disc composed of a non-magnetic material with apertures which retain electromagnets and permanent magnets, and an outer annular disc composed of a ferromagnetic material which is disposed on a side of the inner annular disc, with a non-magnetic isolator ring having curves extending in a serpentine manner. In one embodiment, the curves isolate the electromagnets from the permanent magnets. In another embodiment, the outer annular disc is rotated relative to the inner annular disc to dispose the curves of the serpentine isolator ring in a second position to allow magnetic interaction between the electromagnets and the permanent magnets to generate a second magnetic flux between the permanent magnets and the ferromagnetic surface which decreases adhesion of the wheel to the ferromagnetic surface. A method implements the system.
