  • Publication number: 20240250591
    Abstract: A method of assembling a tandem permanent magnet motor includes the steps of using an external visual reference system to align the stator assembly of the upper permanent magnet motor with the stator assembly of the lower permanent magnet motor. The external visual reference system includes a series of external reference marks that provide a mechanism for quickly aligning the upper and lower permanent magnet motors in the field prior to installation in a well as part of an electric submersible pumping system.

  • Patent number: 11462849
    Abstract: An electrical connector having an electrical conductor member with a first opening and a second opening. Grab rings mounted in the openings have inner diameters containing teeth with crests defining a superimposed inner diameter. The teeth of the grab rings deflect and frictionally engage the outer diameter of the wires to retain them in the openings. A sleeve of insulation material covers an exterior of the conductor member. The sleeve has ends that protrude past the openings and receive an insulation layer of the wires. Resilient electrical contact members are recessed from the grab rings in the openings. The electrical contact members have inner portions biased into contact with the electrical wires and outer portions biased into contact with the conductor member.

  • Publication number: 20170115645
    Abstract: An electronic representation of a network and at least one equipment at the network is received. Intelligent electronic device (IED) information describing at least one IED is received. The at least one IED has an associated plurality of logical IED nodes. A map is created that associates the at least one equipment to an instance of a selected one of the plurality of logical IED nodes. A configuration interface is created and is based upon at least one of the electronic representation of the network, the IED information, and the map. The IED information and the configuration interface are generated automatically.
