    Abstract: Embodiments of laminated stator cores suitable for usage in high temperature applications are provided, as are embodiments of methods for manufacturing high temperature laminated stator core. In one embodiment, the method includes obtaining a plurality of coated laminates each comprising a laminate over which a coating precursor layer is formed. The coating precursor layer contain inorganic dielectric particles having a softening point. The plurality of coated laminates are arranged in a laminate stack, which is then fired at temperatures equal to or greater than the softening point of the inorganic dielectric particles. During firing, a compressive force is applied to the laminate stack sufficient to consolidate the inorganic dielectric particles into a plurality of coherent interlaminate dielectric layers electrically insulating and bonding together the plurality of coated laminates as the high temperature laminated stator core.

    Abstract: A method for additively manufacturing an article includes providing or obtaining a build material, directing a first energy beam at the build material to raise the temperature of the build material above a melting point of the build material, and thereafter withdrawing the first energy beam to allow the build material to solidify into a first layer. The method further includes directing a second energy beam at the first layer, wherein the second energy beam differs from the first energy beam in that the second energy beam is of insufficient energy to cause melting of the first layer of build material and after directing the second energy beam at the first layer, providing additional build material over the first layer. The second energy beam will have an effect of reducing or eliminating residual stresses of each build layer. The energy of the second energy beam can be controlled using a thermal or optical feedback loop. Still further, the method includes directing a third energy beam at the additional build material to form a second layer that is metallurgically fused with the first layer. The process is repeated until an entire 3D shape of desired geometry is completed resulting in a part with reduced of free of residual stress or the potential of cracks within the 3D shape.

    Abstract: Embodiments of a gas turbine engine actuation system are provided, as are embodiments of a high temperature actuator and methods for the manufacture thereof. In one embodiment, the gas turbine engine actuation system includes an actuated gas turbine engine component and a high temperature actuator, which has a rotor mechanically linked to the actuated gas turbine engine component and a stator surrounding at least a portion of the rotor. The stator includes, in turn, a coil support structure having a plurality of spokes extending radially therefrom. A plurality of pre-formed electromagnetic coils 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 in which each of the plurality of pre-formed electromagnetic coils is at least partially embedded.
