Gas turbine engine actuation systems including high temperature actuators and methods for the manufacture thereof

Embodiments of a gas turbine engine actuation system are provided, as are embodiments of a high temperature actuator (64, 68, 72, 80) and methods for the manufacture thereof (100). In one embodiment, the actuation system includes an actuated component and a high temperature actuator, which has a rotor (84) mechanically linked to the actuated component and a stator (82) surrounding at least a portion of the rotor. The stator includes, in turn, a coil support structure (104) having a plurality of spokes (110) extending radially therefrom. A plurality of pre-formed electromagnetic coils (120) is circumferentially distributed about the coil support structure. Each of the plurality of pre-formed electromagnetic coils is inserted over at least one of the plurality of spokes in a radial direction. The stator further includes an inorganic dielectric material (124) in which each of the plurality of pre-formed electromagnetic coils is at least partially embedded.
