The load characteristics of induction motor manufactured by soft magnetic composite (SMC) are presented. We manufactured three kinds of induction motors experimentally. One is a conventional laminated iron core motor. The others are SMC motors. One of the SMC motor uses SMC only for stator, while the other SMC motor uses SMC for stator and rotor. The experimental comparisons of load characteristics and loss analysis are shown. As a result, the difference between the efficiency of the SMC motor and the conventional laminated motor is 4.6%, in spite of the permeability of SMC being 20% lower than the conventional electromagnetic steel.
