Abstract

A radial flux electric machine includes a rotor configured to rotate about an axis of rotation, a plurality of electromagnetic coils, and a stator. The stator may have an annular stator ring and a plurality of core tooth-portions extending in a radial direction. The annular stator ring and the plurality of core tooth-portions may be integrally formed of a Soft Magnetic Composite (SMC). The SMC may include one or more isotropic ferromagnetic materials, a magnetic saturation induction of greater than or equal to about 1.6 Tesla, and an electrical resistivity greater than 10 micro-ohm/m.
