Abstract

The invention relates to an optical fiber measurement device used for a superconducting spherical rotor; an optical axis of a rotary axial optical fiber displacement sensor (3) is coincided with a rotary axis of the superconducting spherical rotor, a rotation speed optical fiber sensor (2) and a motor controlled optical fiber sensor (4) are positioned at both sides of the rotary axial optical fiber displacement sensor (3); the optical axes of the rotation speed optical fiber sensor (2), the rotary axial optical fiber displacement sensor (3) and the motor controlled optical fiber sensor (4) are vertical to a plane (6) at the top part of the superconducting spherical rotor; the three sensors are fixed at a sensor support (1), and the positions thereof are on a straight line. A signal reading graph (5) is etched on the plane (6) at the top part of the superconducting spherical rotor. The measurement device of the invention adopts the non-contact optical fiber sensors for measuring the suspension height of the superconducting spherical rotor and the rotation speed of the superconducting spherical rotor and generating a motor-driven pulse signal for controlling the rotation speed of the superconducting spherical rotor.

Description

technical field [0001] The invention relates to an optical fiber measuring device and a measuring method for a spherical rotor, in particular to an optical fiber measuring device and a measuring method for measuring a low-temperature superconducting spherical rotor Background technique [0002] The continuous development of superconducting materials and low-temperature technology has played a huge role in promoting the development of new precision instruments and equipment. The unique physical properties of superconductors have incomparable application advantages compared with other materials, especially the superconducting magnetic levitation technology has attracted more and more attention. The rotation of the superconducting spherical rotor must first have the stable suspension of the superconducting rotor as a prerequisite. Superconducting magnetic levitation technology has many advantages: firstly, the entire levitation system works in a low-temperature environment, an...
