Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

WHAT IS CLAIMED IS :

1. A method of making an enhanced magnet wire insulation suited for an electric submersible motor application, the method comprising:

drawing copper magnet wire to size;

cleaning the copper magnet wire;

pulling the copper magnet wire through a polyimide wrap machine to produce wrapped copper magnet wire and placing the wrapped copper magnet wire around a spool; heating the wrapped copper magnet wire by unspooling the wrapped magnet wire

through a tube comprising an induction coil;

removing moisture from the heated, wrapped copper magnet wire by creating at least a partial vacuum inside the tube;

redrawing the wrapped copper magnet wire through an extrusion mold after moisture is removed,

applying molten PEEK to the wrapped copper magnet wire to produce enhanced magnet wire; and

winding the enhanced magnet wire into an induction motor to be used to operate an electric submersible pump.

2. The method of claim 1 , wherein heating the wrapped magnet wire comprises heating the wrapped magnet wire to a temperature of 300° F.

3. The method of claim 1 , wherein heating the wrapped magnet wire comprises sliding the wrapped magnet wire through an inside of the induction coil.

4. The method of claim 1 , wherein the at least partial vacuum is created inside the tube by a vacuum pump coupled to an inside of the tube.

5. The method of claim 4, wherein the at least partial vacuum is in a space between the wrapped magnet wire and an inner diameter of the tube.

6. The method of claim 1 , further comprising closing an end of the tube with a rubber plug to at least partially prevent air from entering the tube.

7. The method of claim 1 , wherein winding the enhanced magnet wire into the induction motor further comprises winding the enhanced magnet wire through open slots of a stator of the induction motor, wherein the open slots have empty space around the enhanced

magnet wire.

8. The method of claim 7, further comprising cooling the induction motor by convection by allowing motor oil to flow through the empty space in the open slots around the enhanced magnet wire.

9. The method of claim 1 , wherein the wound enhanced magnet wire is suited for use in temperatures of about 550° Fahrenheit when the induction motor is used to operate the electric submersible pump.

10. A system for making an enhanced magnet wire insulation suited for an electric submersible motor application, the system comprising:

a PEEK wire extruder;

a tube extending between the PEEK wire extruder and a spool comprising polyimide- wrapped copper magnet wire;

the tube comprising:

an induction coil inside the tube;

a vacuum pump operatively coupled to the inside of the tube;

a spool-side of the tube comprising a plug, the plug having an aperture extending through the plug;

wherein the polyimide-wrapped copper magnet wire extends from the spool, through the aperture in the plug, through the tube, and into the PEEK wire extruder.

1 1. The system of claim 10, wherein the tube has at least a partial vacuum inside the tube between the polyimide-wrapped copper magnet wire and an inner diameter of the tube.

12. The system of claim 10, wherein the polyimide-wrapped copper magnet wire extends through an inside of the induction coil as the polyimide-wrapped copper magnet wire extends through the tube.

13. A method comprising:

pulling a magnet wire through a polyimide wrap machine to produce wrapped magnet wire;

heating the wrapped magnet wire in a tube comprising an induction coil;

removing moisture from the heated, wrapped magnet wire by creating at least a partial vacuum inside the tube;

redrawing the wrapped magnet wire through an extrusion mold after moisture is

removed;

applying organic polymer thermoplastic to the wrapped copper magnet wire to produce enhanced magnet wire; and

winding the enhanced magnet wire into an induction motor to be used to operate an electric submersible pump.

14. The method of claim 13, wherein heating the wrapped magnet wire comprises sliding the wrapped magnet wire through an inside of the induction coil.

15. The method of claim 13, wherein the at least partial vacuum is created inside the tube by a vacuum pump coupled to an inside of the tube.

16. The method of claim 15, wherein the at least partial vacuum is in a space between the wrapped magnet wire and an inner diameter of the tube.

17. The method of claim 13, further comprising closing an end of the tube with a rubber plug to at least partially prevent air from entering the tube.

18. The method of claim 13, wherein winding the enhanced magnet wire into the induction motor further comprises winding the enhanced magnet wire through open slots of a stator of the induction motor, wherein the open slots have empty space around the enhanced

magnet wire.

19. The method of claim 18, further comprising cooling the induction motor by convection by allowing motor oil to flow through the empty space in the open slots around the enhanced magnet wire.

20. The method of claim 13, further comprising: prior to pulling the magnet wire,

drawing the magnet wire to size; and cleaning the copper magnet wire.
