Stator end turn protection from partial discharge events in electrical submersible pump (ESP) motors

Abstract

Some implementations include an apparatus comprising a member configured to couple to an end of a stator core of an electrical submersible pump (ESP) motor, the ESP motor to be positioned in a wellbore, wherein the member has a bore through which a motor rotor is to be located, wherein one or more slots are formed in the member around a perimeter of the bore, wherein the member includes a doped material, and wherein the member including the doped material exhibits one or more semiconductive characteristics. The apparatus further includes a laminate material configured to be positioned within at least one of the one or more slots, wherein the laminate material includes at least one of a conductive layer or an insulative layer.
