1. A planar armature for an axial flux machine, the planar armature comprising:
a first layer comprising a first dielectric substrate;
a second layer comprising a second dielectric substrate; and
a third layer disposed between the first layer and the second layer, wherein the third layer comprises:
first conductive traces that form at least first portions of windings for at least a first pole of the planar armature,
a first quantity of a magnetic composite material disposed in interstices between the first conductive traces within at least a first region of the third layer, wherein the magnetic composite material comprises particles of a soft magnetic material embedded within a first dielectric material and the first region is located within an active area of the axial flux machine, and
a second quantity of a second dielectric material disposed within at least a second region of the third layer, wherein the second dielectric material is free of the soft magnetic material and the second region is located outside of the active area.
