Claim 15:
16. A method of making a stator core component for an axial flux motor comprising:
introducing a soft magnetic composite material (SMC) precursor into a cavity of a mold comprising a first region and a second region, wherein the soft magnetic composite material (SMC) precursor comprises a polymer precursor and a plurality of magnetic or ferromagnetic particles; and
compressing the soft magnetic composite material (SMC) precursor in the cavity by concurrently applying a first pressure of greater than or equal to about 800 MPa from a first press head in the first region and a second pressure of greater than or equal to about 300 MPa to less than or equal to about 600 MPa from a second press head in the second region; and
removing a consolidated soft magnetic composite (SMC) material component from the cavity having a first density corresponding to the first region where the first pressure is applied and a second density corresponding to the second region where the second pressure is applied.
