  • Electrical discharge prevention in bearing for submersible pump motor using a conductive spring between a sleeve and a carrier body
    Patent number: 10797555
    Abstract: A submersible pump electrical motor has a bearing sleeve between first and second rotor sections and mounted to the shaft for rotation in unison. An insert sleeve surrounds the bearing sleeve. A carrier body surrounds the insert sleeve. A carrier anti-rotation ring on an outer diameter of the carrier body engages the bore of the stator. First and second seal rings are axially spaced apart from each other between an outer diameter of the insert sleeve and an inner diameter of the carrier body. A hole in the carrier body has an inner end at the inner diameter of the carrier body. An electrically conductive coil spring within the hole has an inner end protruding through the inner end of the hole into contact with the outer diameter of the insert sleeve, creating electrical continuity between the insert sleeve and the carrier body.
