Abstract

The real-time displacement analysis and correction of vibration forces on the rotor of a rotational active magnetic bearing (AMB) system were performed. The real-time system performs four main tasks: fault detection, fault diagnosis, error correction and fault identification. Historical fault data from a fully suspended 250 kW water cooling AMB pump was used in the design process of the fault detection system. A double radial AMB test rack was used to test the effectiveness of the proposed real-time system. The real-time system corrected, identified and minimized the vibration forces to a stable working condition.
