Magnetic thrust bearing for three phase electric-energy meter

Disclosed is a magnetic thrust bearing for a three phase electric-energy meter. The utility model is characterized in that magnetic loops are arranged in an upper and a lower bearing blocks, and the circular disc of the electric energy meter can be supported by the repulsion force of the same polarities between the magnetic loops; meanwhile, a carbon bearing is arranged in the upper magnetic loop in the upper bearing block, and the rotations of the circular disc of the electric energy meter can be supported through the matching between a guide needle and the carbon bearing. Lubricating-oil is unnecessary to be added at the site of rotations, and the magnetic thrust bearing is free from the influences of temperature and moisture. The utility model has the advantages of small friction forces, steady and flexible rotations, long service life, etc.
