Recently, air pollution policies have been actively implemented Internationally. The regulations for carbon-producing products are gradually being strengthened with the aim of creating a low-carbon green village. Moreover, to reduce carbon emissions from automobiles, an eco-friendly vehicle such as electric vehicles (EVs), hybrid electric vehicles (HEVs), and fuel cell electric vehicles (FCEVs) are recommended. In particular, for EV structure, the electric motor is the most important part since it acts as a combustion engine of the conventional vehicle. Thus, the energy efficiency improvement of the electric motor will be one of the biggest concern increasing the mileage of the EV. In this paper, the effect of the magnetic materials was analyzed in the aspect of energy efficiency of the EV traction motor. First of all, the concept model for EV vehicle was adopted and depicted in Fig.1. The type of this motor is the interior permanent magnet synchronous motor (IPMSM) with 8 poles and 48 slots. The shape of the permanent magnet inserted in the rotor is 1-layer U-shape. The permanent magnet and the electrical steel sheet used for this model are N39UH and 50PN470 respectively.
