Abstract
A device and a method for inhibiting vibration of a superconducting magnetic suspension rotor. The device comprises a rotor cavity housing, lateral coils, a superconducting rotor with a rotor top plane, a copper plate, pole shoes, a z-axial vibration measuring sensor, an x-axial vibration measuring sensor, a y-axial vibration measuring sensor, and a copper ring, the pole shoes having a spherical inner surface and being arranged symmetrically up and down so as to form a rotor cavity; the annular lateral coils being closely adjacent to an outside cylindrical surface of the rotor cavity housing and fixed to the same; the z-axial vibration measuring sensor being fixed to a central region of the copper plate; the x-axial vibration measuring sensor being mounted along an x-coordinate axis and the y-axial vibration measuring sensor mounted on a on the copper ring which is mounted along an equatorial plane of the rotor.
