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.
