Claim 0:
1. A metallic coupler for a polymeric rotor, the metallic coupler comprising:
a cylindrical core that is configured to receive a drive shaft; and
an outer ring that extends around the cylindrical core and defines an upper planar surface and a lower planar surface that extend outward from an outer surface of the cylindrical core, the outer ring including an outward-facing cylindrical surface that extends between the upper planar surface and the lower planar surface, wherein
a plurality of recesses are defined within the outer ring and extend into the outer ring through at least one of the upper planar surface and the lower planar surface;
the plurality of recesses are configured to receive at least one polymeric material;
the plurality of recesses are defined between the outer surface of the cylindrical core and the outward-facing cylindrical surface of the outer ring; and
the plurality of recesses are further configured to rotationally and axially secure a rotor frame that is formed of the at least one polymeric material.
