Recently, electric vehicles (EVs) receive considerable attention as one of the eco-friendly vehicles because of the regulations of environmental pollution. Among various studies related to EVs, studies about improving fuel economy of EVs have been actively performed. In this paper, since the interior permanent magnet synchronous motors (IPMSMs) are widely used for EV traction, the optimum design considering efficiency at main operating points of IPMSM for traction was conducted to improve the fuel economy of EV. To determine the main operating points, EV simulation was performed using Powertrain Blockset in Matlab/Simulink. Then, by using desirability function, the optimum design considering efficiency at main operating points of traction motor was carried out, considering the constraint conditions. Finally, it was confirmed that efficiency and fuel economy of the optimum model was improved compared with those of the initial model.
