An electrical motor for an electrical submersible pump wherein the
electrical motor has increased heat transfer capabilities. The electrical
motor includes a housing and a plurality of stator laminations within the
housing. Each stator lamination defines a central orifice and a plurality
of lamination slots. A plurality of magnet wires pass through each of the
plurality of lamination slots formed by the stacked plurality of stator
laminations. Shrink wrap surrounds each of the plurality of magnet wires
to secure the magnet wires in bundles. The result is that the wires are
effectively bound together in a manner that allows oil to move freely
inside the lamination slots surrounding the wire bundles. Since fluid can
pass between and around the windings, the overall winding temperature
will be normalized, essentially reducing hot spots that occur in prior
art designs.
