Publication number: 20240146125Abstract: An electric machine with a low profile retention assembly for retention of a stator core is disclosed. A first housing houses the stator core. The first housing has an axial end face with a circumferentially extending, shaped profile having recessed portions that project axially inward alternating with non-recessed portions. A portion of the stator core extends axially out from the recessed portions. A core retention spring is disposed circumferentially at the axial end face of the first housing. The core retention spring has direct contact with the portion of the stator core that extends axially out from the recessed portions of the first housing and the shaped profile of the housing. The core retention spring pushes against the portion of the stator core that extends that extends axially out from the first housing, imparting one or more of an axial load and radial load into the stator core.Type: ApplicationFiled: October 28, 2022Publication date: May 2, 2024Applicant: GENERAL ELECTRIC COMPANYInventors: MATTHEW ROBERT MARTIN, PHILIP MICHAEL CIOFFI, JOHN RUSSELL YAGIELSKI, WEI ZHANG

Publication number: 20240128695Abstract: An approach for facilitating mechanical and electrical connection of electric machines and electrical components in an electrical system using connectors with quick connect/disconnect electrical connectors is disclosed. Each quick connect/disconnect electrical connector can be placed on the end of an electrical power distribution cable that connects with an electric machine or electrical component. The electric machines and electrical components and the electrical power distribution cables can have hollow coolant passages formed therein to receive cooling fluid from a cooling device for direct cooling of the electric machines, electrical components and the electrical power distribution cables.Type: ApplicationFiled: October 18, 2022Publication date: April 18, 2024Applicant: GENERAL ELECTRIC COMPANYInventors: MATTHEW ROBERT MARTIN, JOHN RUSSELL YAGIELSKI, PHILIP MICHAEL CIOFFI, MARK EDWARD DAME, WEI ZHANG

Publication number: 20230336045Abstract: An electric component for an electric machine includes a body having slots defined therein, and a conductive winding extending out of axial end(s) of the slot(s). The electric component may include any electric machine component having conductive windings, e.g., a stator for a generator. The electric component includes a resin dam around the conductive winding at axial end(s) of the slot(s). The resin dam blocks liquid communication through at least a space between the conductive winding and an inner surface of the slot(s), during manufacture. The electric component also includes a (solidified) insulating resin in the slot(s) and against the resin dam(s) at the axial end(s) of the slot(s). Any number of the conductive windings and slots may include a resin dam, e.g., one, some or all. The resin dams ensure complete filling of the slots and encapsulation of the conductive windings.Type: ApplicationFiled: April 13, 2022Publication date: October 19, 2023Inventors: Matthew Robert Martin, Karim Younsi, Nolan Gregg Curwen, Wei Zhang, John Russell Yagielski

Patent number: 10415741Abstract: A system for laterally moving an industrial machine is provided. The system includes a pair of rail elements configured to be positioned laterally below and support the industrial machine, the rail elements allowing the industrial machine to be moved laterally from a first operative position to a second, maintenance position; and a pair of linear actuators configured to laterally move the industrial machine as from the first, operative position to the second, maintenance position. The rail elements may include a first skid configured to couple laterally to an underside of the industrial machine at a first axial position; and a second skid configured to couple laterally to an underside of the industrial machine at a second axial position. First and second segmented support rails are positioned in sliding, aligned contact with the first and second skid, respectively, and are configured to be supported on a respective machine foundation.Type: GrantFiled: July 20, 2018Date of Patent: September 17, 2019Assignee: General Electric CompanyInventors: Michael Alan Davi, Max Dryden, Jayan Kaadaapuram George, Jonathan Peter Mallory, Matthew Robert Martin, Sean Cornelius O'Meara, Cornelis Antonius Fransiscus Segeren, John Russell Yagielski

Patent number: 10224776Abstract: A retention assembly for retaining a plurality of elements in a stator slot of an electric machine is provided. The retention assembly may include a stator wedge fixedly positioned in a dovetail in the stator slot to retain the plurality of elements; a top ripple spring between the plurality of elements and the stator wedge; and at least one shim positioned between the stator wedge and a load bearing surface of the dovetail. A method may include compressing the stator wedge in the stator slot from a first position thereof relative to the dovetail of the stator slot, the compressing creating a gap between the stator wedge and the dovetail. A shim may be inserted in the gap; the compressing released such that the shim retains the stator wedge in a second position that is more compressed relative to the plurality of elements in the stator slot compared to the first position.Type: GrantFiled: June 3, 2015Date of Patent: March 5, 2019Assignee: General Electric CompanyInventors: Eric Steven Buskirk, Andrew Duane Brown, James Jonathan Grant, Curtis Maurice Hebert, Benjamin Alber Mancuso, Matthew Robert Martin, Jessica Mary Powers

Patent number: 10208862Abstract: A seal ring assembly includes a first seal ring axially disposed from a second seal ring. The first seal ring has an axial face opposing an axial face of the second seal ring. A radial oil channel is defined between the two axial faces. Both seal rings have a tapered surface configured to contact a spring. The spring biases the seal rings away from each other via the tapered surface. Both seal rings are disposed in a radially inwardly directed channel. At least one of the seal rings have a plurality of protrusions that extend beyond the axial face. The protrusions are configured to create a passageway to allow oil to flow through the passageway and to allow at least one of the seal rings to move into a desired position by reducing static friction between the axial faces.Type: GrantFiled: January 13, 2015Date of Patent: February 19, 2019Assignee: General Electric CompanyInventors: Daniel James Fitzmorris, Anthony James George, Anthony Salvatore Arrao, Anand Shankar Tanavde, Matthew Robert Martin
