Abstract

This paper sets forth a design paradigm for a permanent magnet synchronous machine (PMSM) architecture that employs rotational asymmetry to obtain an improved constant power speed range performance and increased torque density. A population-based multiobjective optimization design approach is used to design the new machine topology and compare it to a conventional symmetrical surface mounted PMSM. Results obtained demonstrate that improved performance is attainable with the asymmetrical design. Validation of the results is carried out by means of three-dimensional finite element analyses.
