HIGH EFFICIENCY SUBMERSIBLE ELECTRIC MOTOR AND COMPONENTS

摘要

The magnetic members of the motor and/or a related magnetic bearing has poles (52) formed by laminations of a magnetic sheet material and slots (60) are formed between poles and are filled with material such as epoxy (65) to form a smooth circumferential surface and bridges the gaps between the laminations in a continuous manner. The coating has a thickness that does not substantially increase the magnetic pole gap and comprises a wear resistant, nonconductive and nonmagnetic solid fiber that seals the exposed surfaces of magnetic components permitting operation in direct contact with corrosive process fluids.
