Abstract

The invention discloses a superconducting low-temperature rotary experiment table which comprises a main shaft, a bearing support system, a strong-current slip ring, a weak-current slip ring, magnetic fluid sealing equipment, a driving device and a rack, wherein the bearing support system and the driving device are fixedly arranged on the rack; the main shaft is connected with the bearing support system by virtue of a bearing; one end of the main shaft is connected with and supports a to-be-tested superconducting rotor by virtue of a cantilever, and the other end of the main shaft is connected with magnetic fluid sealing equipment; the strong-current slip ring is adjacent to the to-be-tested superconducting rotor and is arranged on the main shaft in a sleeving manner. The superconducting low-temperature rotary experiment table is capable of reliably supporting the superconducting rotor of a superconducting motor and driving the superconducting rotor to rotate; in a rotation process, a cooling medium, a driving and a control circuit and a sensing circuit can be supplied to a refrigeration system of the superconducting rotor, so that the work conditions of the refrigeration system are ensured, sensing signals of temperature, stress and the like of the rotor are transmitted to the ground, and the superconducting rotor can be replaced conveniently, so the implementation of the refrigeration system of the superconducting motor is met.

Description
