SUPERCONDUCTING MAGNETIC SUSPENSION Russian patent published in 1994 - IPC

FIELD: precision instrument engineering. SUBSTANCE: layer of non-superconducting material 3 is applied onto superconducting surface of inertial body 2. Thickness of layer is equal to , where H_o is nominal strength of magnetic field in working space of the suspension, H_кр is critical value of strength of magnetic field for superconducting material of inertial body, d_o is nominal working space between short-circuited superconducting coils and inertial body, K is strength restriction coefficient of maximal magnetic body. Inertial body moves under effect of acceleration; in this case one working space increases, and the other one decreases. Magnetic force increases in the reducing space, as strength of field increases (the force is proportional to magnetic field strength squared). Force reduces in the increasing space. Arise of the force is directed in opposite to effect of acceleration. Inertial body stops to move when balance between the forces is achieved - when inertial and magnetic forces are equal. EFFECT: improved reliability. 1 dwg
