| Abstract: | This article presents an incomplete spherical superconducting rotor. A set of static balance tooling and detection methods for the special rotor were designed to improve the existing flotation measuring device with a flotation method. In this method, two toolings with different weights and superconducting rotors were assembled and flotation was attained via pressurized gas bearing. Then the rotor was floated by the gas bearing. And the unbalanced azimuth angle can be measured through high-precision electric eddy current sensor by three point pick-up method. According to the calculation formula of the imbalance, rotor unbalance quantity and range can be acquired. |
