Abstract
The high temperature superconducting magnetic levitation bearing (HTSMB) uses the special magnetic flux pinning properties of the high temperature superconductor and the full diamagnetic effect of the Meissner effect to make the rotor achieve self-stable suspension. Compared with electromagnetic bearings (AMB), superconducting magnetic suspension bearings do not require a control system and have lower energy losses. This paper analyzes the levitation characteristics of a new high-temperature superconducting magnetic levitation bearing using a frozen-image model. The results show that the levitation force and stiffness of the bearing change with the changes of the initial cooling gap, axial displacement and radial displacement of the bearing. Under the same conditions, the radial suspension force is an order of magnitude greater than the axial suspension force; Within a certain range, the smaller the initial cooling gap, the better the suspension performance of the bearing, and the hysteresis characteristics have little effect on the suspension characteristics of the bearing.
