Study on Parametric Design of Traction Motor and Dynamic Performance of Electric Vehicle

This paper study the dynamic performance of electric vehicle (EV) by analyzing the traction motor parameters. Using the interior permanent magnet synchronous motor (IPMSM) as the traction motor, the characteristics of motor, such as maximum torque, power factor, constance power speed ratio, and maximum speed are estimated by the saliency ratio of inductance and flux linkage. Then, the relationships between these characteristics and the dynamic performance of EV are established. Thus, the influence of the parameters of the traction motor on the dynamic performance of EV is revealed.
