Method for external winding of esp motor using a split core stator

A method for manufacturing a stator for an electric submersible pump, the method comprising:

• forming a stator core having an inner portion and an outer portion, the inner portion of the stator core having a plurality of teeth forming a plurality of slots therebetween, each of the slots having a radially-outward-facing opening, the outer portion of the stator core being adapted to fit over the inner portion of the stator core and to thereby close the plurality of slots of the inner portion of the stator core;
• prior to mounting the outer portion of the stator core over the inner portion of the stator core, forming a plurality of magnet wire coils on the inner portion of the stator core, wherein forming the plurality of magnet wire coils on the inner portion of the stator core comprises
• placing the inner portion of the stator core in a stationary position, and
• for each coil, positioning the magnet wire on the inner portion of the stator core while preventing each winding of the magnet wire from sliding axially with respect to adjacent windings of the magnet wire;
• and
• after forming the plurality of magnet wire coils on the inner portion of the stator core, mounting the outer portion of the stator core over the inner portion of the stator core and thereby closing the plurality of slots of the inner portion of the stator core.
