The main aim of this work is to determine the optimal shape design of a class of Interior Permanent-Magnet (IPM) motors for electric vehicles (EV), by means of many-objective optimisation which is an emerging area in the automated optimal design. As the case study, a 3-phase, 4-pole single-barrier IPM motor is modelled by means of using finite-element analysis. The goal is to optimise the motor’s performance in terms of a number of design criteria such as the power losses, running torque, torque ripple and material costs, by varying size and position of the permanent magnet and flux barriers.
