Abstract

This paper deals with the optimal design of V-shape interior permanent-magnet motor (V-IPM) for the electric vehicle application. The magnetic equivalent circuit (MEC) is used to obtain the performing parameters of the studied motor. The applied analytical model is verified using finite-element analysis (FEA). Considering the voltage and current limits, the maximum torque per ampere (MTPA) is applied to determine the optimum number of turns per slot to have a wider constant torque region. The consideration of the MTPA for the machine design increases the electric motor volume. The volume minimization is targeted in the objective function of the optimization problem. The optimization is executed over three different driving cycles for a 50-kW V-IPM motor. The efficiency and power factor are the constraints of the optimization problem. The optimal designs are compared against each other in terms of their efficiency and power density. The simulation results depict how the magnet and iron volume vary in different driving cycles.

OtherThe theme of this year’s conference is Clean and Reliable Electric Energy Systems. With the prevalent problem of climate change, clean energy technologies are gaining much attention in the power industries currently. At the same time, due to intermittent nature of renewable sources, power system reliability and security are also being given serious considerations. It is, therefore, imperative that this premier power engineering conference in this region gives proper acknowledgement to the need of the future power delivery system.
