The application of Soft Magnetic Composites (SMC) to a Transverse-Flux Permanent Magnet (TFPM) machine is studied. Four SMC material and pressing methods are investigated for high saturation flux density. Low dielectric content, Die Wall Lubrication and cold pressing allow the best combination of high material density (7.45 g/cm 3), high saturation flux density (1.53 T) and good mechanical resistance (65 MPa). 624 Flux concentrators were produced with SMC material and inserted in the rotor of a TFPM machine with toothed rotor. Torque and flux measurements are presented and are validated with finite element analysis.
