FIELD: physics.
SUBSTANCE: invention relates to the field of physics of magnetism and can be used as a wheel on a magnetic cushion, instead of the rolling bearing of a wheel, as applied to the operation of a mobile device on wheel-travel. In two coaxially arranged cylindrical magnets, the cylindrical bases are located in two planes perpendicular to their common axis, and the cylindrical surfaces are located with an air gap between the outer diameter of the central and inner diameter of the peripheral magnets, while the magnets tend to maintain the uniformity of the gap when the force acting on them is perpendicular to their axis under the condition of the radial directions of their magnetic fluxes. Device comprises a stationary shaft and a wheel rim, with the coaxial fixed shaft and mechanically connected to it an inner central cylindrical electromagnet having a groove with a coil located there, the winding of which is made of an insulated wire of electrical steel. Coaxially to the central electromagnet through an air gap an external cylindrical electromagnet is located mechanically connected to the inner surface of the wheel rim. In this case, the internal electromagnet in the upper part has a large area of the lateral cylindrical surface with respect to the lower part of its lateral cylindrical surface. In addition to the shaft of the wheel, a limit switch is attached, which signals the inclusion of an additional coil located at the top of the internal electromagnet.
EFFECT: providing a stable magnetic suspension in all three coordinates in space.
