Maglev pump is widely requested for artificial heart or chemical industries. Hybrid magnetic bearing is recognized as an high efficient one even with wide airgap and is suitable for such applications. This paper proposed two types of hybrid magnetic bearing for maglev pump. The results of magnetic field analysis for internal permanent magnet (IPM) type one are introduced. Then the experimental setup and its fundamental characteristics are explained. The results show stable levitation, but it has dynamical problems. To improve dynamic characteristics, control system has changed from local to centralized PID controller. The results show promising characteristics for practical use.
