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.

A splice connects a lower coiled tubing segment containing a lower power cable segment to an upper coiled tubing segment containing an upper power cable segment. The splice has a lower terminal electrically connecting together upper ends of lower power conductors. An upper terminal electrically connects together lower ends of upper power conductors. An electrical intermediate connector has an upper end that stabs into engagement with the upper electrical terminal and a lower end that stabs into engagement with the lower electrical terminal. A load supporting member surrounds the intermediate connector and joins to upper and lower ends, respectively, of the lower coiled tubing segment and the upper coiled tubing segment.

Electric submersible well pumping systems operable in well temperatures of above about 180&#xb0; C. (356&#xb0; F.) utilize high temperature electrical insulation. The electrical insulation includes E-base polyimide films or perfluoropolymer TE films on various components. The insulation films are employed around magnet wires that are threaded through slots in the stator. Slot insulation of E-base polyimide or perfluoropolymer TE film surrounds the magnet wires in the stator slots. Sheets of E-base polyimide or perfluoropolymer TE film extend around and between phase loops of the magnet wire at the lower end of the stator. The motor contains a PAO oil having additives to dissipate acid generated by epoxy used in the motor.
