Abstract

See full text

Systems and methods for electric motor, where the stator core has one or more stator core sections, each of which is a single-piece unit formed of soft magnetic composite (SMC) material, and where the stator core sections are positioned end-to-end with seals at each end to form a plurality of stator slots, where each of the stator slots extends through each of the stator core sections and is in fluid communication with the others to form a sealed stator chamber. The sealed stator chamber may have an expansion chamber to allow expansion and contraction of dielectric fluid in the stator chamber while maintaining separation of the dielectric oil from lubricating oil which is within the motor but external to the stator chamber. The sealed stator chamber can prevent well fluids that leak into the motor from reaching the stator windings and degrading their insulation.
