  • Rotor slot liners
    Patent number: 9667112
    Abstract: A slot liner for a rotor assembly in one embodiment includes a metallic support member and a coating. The coating is disposed on at least one side of the metallic support member, and includes a mixture of a filler and a polyimide resin. The filler is a high thermal conductivity electrical insulating (HTCEI) filler, and includes particles of at least one of boron nitride, aluminum nitride, or a diamond material.
    Type: Grant
    Filed: August 28, 2014
    Date of Patent: May 30, 2017
    Assignee: General Electric Company

  • Method of making a heat transfer element for an electric machine
    Patent number: 9543814
    Abstract: An electric machine, such as a generator, providing for the generation of electricity and includes a rotor generating a magnetic field and a stator having stator windings. The interaction of the magnetic field with the stator windings generates current in the windings. The generator may provide the generated current to a power output of the generator, where it may be further transmitted to an electrical load to power the load.
