Abstract

The invention relates to a device for detecting the rotating position of a superconductive spherical rotor, which comprises a hollow rotor (5), a stator framework (1), a drive coil (2), a field coil (3) and a detection coil (4), wherein the drive coil (2), the field coil (3) and the detection coil (4) are all arranged in the middle of the stator framework (1). The rotation position of the superconductive spherical rotor is detected through the position change of a magnetic field generated by the field coil (3) in a rotor rotating inner hole window (6) and the change of induced voltage obtained by the detection coil (4). The device for driving a low-temperature superconduction spherical rotor to rotate is simple and convenient, has higher detecting and controlling precision, consumes no energy and can further increase the rotating and the driving precision and efficiency of the superconductive spherical rotor.

Description

technical field

[0001] The invention relates to a rotor rotation position detection device, in particular to a device for detecting the rotation position of a superconducting spherical rotor. Background technique

[0002] With the continuous development of superconducting materials and low-temperature technology, superconducting maglev technology has become more and more widely used in various fields, such as superconducting maglev trains, superconducting maglev bearings, superconducting flywheel energy storage, gravity accelerometers, etc. . 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. Due to the complete diamagnetism of superconductors, that is, the Meissner effect, stable superconducting magnetic levitation can be obtained, and at the same time, this non-contact levitation can run stably without ...
