Field Dynamic Balancing System Based on Labview in AMB-Flexible Rotor System

The 10MW high temperature gas-cooled test module reactor (HTR-10GT) with the core made of spherical fuel elements was designed and constructed by the Institute of Nuclear and New Energy Technology of Tsinghua University in China. In the HTR-10GT,turbo-compressor and generator rotors are connected by a flexible coupling and a decelerator. The AMB is the important technology for the helium blower. AMB rotor commonly has high working speed, although on the theory base, you can raise winding rigidity at discretion through feedback control, in fact, because of the limit of AMB power, if dynamic balancing is not good, it will easily cause electric current saturated phenomenon and make the base of bearings cause fierceness vibration. SO it is quite essential to make precision dynamic balancing for high speed AMB rotor. In this paper significance of dynamic balance for the AMB system is discussed and as well vibration monitoring and field dynamic balance system for the AMB system is constructed. The feasibility of the dynamic balance system is tested through experiments in the paper.
