Patent number: 11606012Abstract: A method includes forming elongated magnetic flux carrier portions in magnetically conductive sheets by cutting elongated magnetic flux barriers including one or more relief features into the magnetically conductive sheets, such that the magnetic flux barriers are separated from each other in radial directions of the magnetically conductive sheets. The method includes inserting or forming non-magnetic posts into the magnetic flux barriers such that each of the non-magnetic posts is elongated in a different radial direction of the radial directions from a first magnetic flux carrier portion to a second magnetic flux carrier portion of the magnetic flux carrier portions on opposite sides of at least one magnetic flux barrier; and forming at least part of a rotor for an electric machine assembly using the magnetically conductive sheets having the magnetic flux carrier portions, the non-magnetic posts, and the magnetic flux barriers.Type: GrantFiled: June 24, 2021Date of Patent: March 14, 2023Assignee: General Electric CompanyInventors: Anoop Jassal, Mohamed Osama, Konrad Weeber, Joseph Zierer

Patent number: 11095198Abstract: An electric machine assembly includes a rotor formed from one or more magnetically conductive sheets having elongated magnetic flux barriers separated from each other in radial directions that radially extend away from an axis of rotation of the rotor. The magnetic flux barriers are separated from each other by magnetic flux carrier portions of the one or more magnetically conductive sheets. The assembly also includes a non-magnetic post coupled with the magnetic flux carrier portions of the one or more magnetically conductive sheets on opposite sides of at least one of the magnetic flux barriers. The non-magnetic post is elongated in the radial directions from a first magnetic flux carrier portion to a second magnetic flux carrier portion of the magnetic flux carrier portions on the opposite sides of the at least one magnetic flux barrier.Type: GrantFiled: September 28, 2018Date of Patent: August 17, 2021Assignee: General Electric CompanyInventors: Anoop Jassal, Mohamed Osama, Konrad Weeber, Joseph Zierer

Patent number: 6764280Abstract: A multi-bladed tail rotor assembly is disclosed that provides higher aerodynamic performance, damage tolerant design with 10,000-hour life expectancy, and which requires low maintenance through the use of composites and elastomerics. The tail rotor hub assembly includes two stacked yoke assemblies having multi-bladed teetering rotors, each mounted on a single drive mast. Each yoke assembly includes a yoke hub having a transverse bore therethrough, a bearing assembly disposed within the bore, and retention means for aligning and securing the bearing assembly within the bore. Each bearing assembly includes a trunnion portion having trunnion arms that extend outwardly from a trunnion body portion, and an elastomeric bearing disposed about each trunnion arm. The tail rotor assembly utilizes a composite twist strap flexure to accommodate collective pitch control integral with each rotor blade.Type: GrantFiled: March 4, 2002Date of Patent: July 20, 2004Assignee: Bell Helicopter Textron Inc.Inventors: Ajay Sehgal, Cecil Covington, David Haynie, Joseph Zierer, Eric Boyle
