We have developed a high-efficiency (IE5 class), 11kW axial-flux permanent magnet motor (AFPM) with ferrite magnets and amorphous cores. In this study, we examined a high-power AFPM under the same volume as the 11kW AFPM. To increase the motor power, the torque and rotation speed were improved more than those of the 11kW AFPM. In particular, Sm-Fe-N (Samarium-Iron-Nitrogen) magnets are used in rotors to improve the torque. Consequently, the prototype of 44kW (85Nm, 4950r/min) AFPM could achieve efficiency standard IE 5 (>96.0%).
