EMBEDDED ELECTRIC MACHINE
First Claim
1. A gas turbine engine defining a radial direction and an axial direction, the gas turbine engine comprising:
- a compressor section and a turbine section arranged in serial flow order, the compressor section and turbine section together defining a core air flowpath;
a rotary component rotatable with at least a portion of the compressor section and with at least a portion of the turbine section;
a static frame member; and
an electric machine rotatable with the rotary component, the electric machine positioned at least partially inward of the core air flowpath along the radial direction, the electric machine flexibly mounted to the static frame member, or flexibly coupled to the rotary component, or both.

Abstract
A gas turbine engine includes a compressor section and a turbine section together defining a core air flowpath. The rotary component is rotatable with the compressor section and the turbine section. The gas turbine engine additionally includes an electric machine rotatable with the rotary component and positioned coaxially with the rotary component at least partially inward of the core air flowpath. The electric machine is flexibly mounted to a static frame member, or flexibly coupled to the rotary component, or both, such that the electric machine is mechanically isolated or insulated from various internal and external forces on the gas turbine engine.
