In motor design, an important factor is the content of silicon in coss material, which can effect the saturation of magnetic circuit and coss loss. While the content of silicon is high, the core loss will be reduced. At the same time, in order to assure the effective flux, the magnetizing current must be increased and then the copper loss becomes higher. Therefore the material with high content of silicon, which is used in the motor, can not always give the high efficiency. In this paper flux linkage of two different material s10 and s60 is compared according to the operating region and then exciting current to obtain same flux is estimated. By comparing core loss and copper loss between two material with the estimated current and flux linkage, this paper presents a criterion in determining the material for higher efficiency
