A comparative study of optimally designed V-shaped magnet IPM synchronous motors

This paper conducts a comparative study on the predicted operating characteristics of a series of optimally designed concentrated-winding, V-shaped magnet Interior Permanent Magnet Synchronous Motors (IPMSMs). A local optimizer (nonlinear Simplex) and a global optimizer (Genetic Algorithm (GA)) are separately used to determine the dimensions of each optimized machine based on three distinctive Objective Functions (OFs) to (i) minimize the weight, (ii) minimize the electromagnetic losses, and (iii) minimize the losses and weight in a multi-objective solution. In order to conduct the experimental analysis and verify the predictions, a prototype of the optimized machine is fabricated.
