The invention discloses a superconducting magnetic suspension rotor attitude measurement signal calibration device. A main shaft of a high speed rotation motor (10) is used for simulating the suspension and the high speed rotation of a superconducting magnetic suspension rotor (8). The rotation speed of the high speed rotation motor (10) is controlled by a frequency converter. The superconducting magnetic suspension rotor (8) is arranged on the end face of the motor main shaft (11). The axis (12) of the motor main shaft passes through the center of the superconducting magnetic suspension rotor (8) in the space, and is perpendicular to the plane of the end part of the superconducting magnetic suspension rotor (8). The axial precision and the radial precision of a rotation shaft (3) of a horizontal rotation platform (2) are less than 0.1 micron, so as to realize rotation positioning of small angle. A stepper motor drives the horizontal rotation platform (2) to rotate, and angle positioning is realized by a positioning locking device (4). The axis (13) of the rotation shaft (3) of the horizontal rotation platform (2) and the axis (12) of the motor main shaft intersect in the space, and the intersection is the center of the superconducting magnetic suspension rotor (8).
Description
technical field [0001] The invention relates to a calibration device for attitude measurement signals of a superconducting magnetic levitation rotor. Background technique [0002] Since the discovery of superconductivity, its unique zero-resistance characteristics and complete diamagnetism (also known as the Meissner effect) have been widely used in various fields such as magnetic bearings, flywheel energy storage, high-speed motors, gravity measurement and precision instruments for scientific experiments. Applications. A superconducting precision instrument that uses the Meissner effect of superconductors to realize the suspension and high-speed rotation of superconducting rotors, with extremely high precision and extremely low energy loss.
