Abstract

Repulsive type magnetic bearing consisting of permanent magnets (PM) and controlled current electromagnets have the advantages of less number of electromagnets and simplified control circuit compared to active magnetic bearing. The system is fundamentally unstable one and is very prone to disturbance. The shape and configuration of permanent magnet has a strong influence on the stability of the system. Two model of repulsive type magnetic bearing have been designed and fabricated in our laboratory. Repulsive forces and stiffness characteristics for different PM configurations have been studied and suitable configuration have been chosen. This paper investigates a method of disturbance attenuation and faster stabilization via permanent magnet configuration on repulsive type magnetic bearing.
