In chemical plants, anticorrosion magnetic drive pump is commonly used to deliver corrosive chemical liquid because of its high anti-corrosion performance. However, when bubbles enter in the chemical pump and accumulate between the shaft and the bearing, the shaft is often broken by thermal shock. The magnetic bearing which holds the rotor in non-contact has a good advantage to avoid thermal shock and to keep the rotor in a stable state by restoring force induced from eddy current in the conductor. The model of magnetic bearing was analyzed using three dimensional finite element method. In this model, the restoring force of 68.6N and the braking torque of 8.7N·m were obtained. The locus of rotation axis was also estimated from a radial load and a drag coefficient. The rotor may locate inside the movable range.
