    Date of Patent: December 17, 2024
    Assignee: Rolls-Royce Corporation
    Inventors: Rama Krishna Shanmukha, Anand Mathivanan, Jenn Yen Loh
  • ELECTRIC MACHINE WITH COMBINED ROTOR AND COOLING FAN
    Publication number: 20240055948
    Abstract: An electric machine for use in an aircraft propulsion system includes a shaft, a magnetic rotor drum, and a rotor hub. The shaft extends along an axis and is configured to rotate about the axis. The magnetic rotor drum includes a rotor that extends circumferentially around the axis and a plurality of magnets that are arranged circumferentially around the rotor. The rotor hub extends radially between and interconnects the shaft and the rotor. The rotor hub is configured to move air along the electric machine to cool components thereof in response to rotation of the shaft about the axis.
