Abstract:
This paper presents the electromagnetic design optimization for a 12-slot, 8-pole, concentrated winding, V-shaped magnet Interior Permanent Magnet Synchronous Motor (IPMSM) using a Genetic Algorithm (GA). Three distinct objective functions are considered. These include minimum weight, minimum loss, and a combined multi-objective function to minimize both the weight and the losses. The three optimized machines are compared with a non-optimized preliminary design using 2D-Finite Element Analysis (FEA). The multi-objective optimal design shows major efficiency improvements (1.25%) and weight reduction (0.918 kg) compared to the preliminary design. Sensitivity analysis is conducted on this optimized machine, which evaluates its weight and efficiency variations as a function of deviations in the optimized variables.
