Study on the impact of uncertain design parameters on the perfomances of a permanent magnet assisted synchronous reluctance motor

In this paper, deterministic and robust design optimizations of a permanent magnet assisted synchronous reluctance machine were performed to study the impact of different uncertain input parameters on the design. These optimizations were carried out using a surrogate model based on 2-D finite element simulations. Different robust optimizations considering geometric and magnetic uncertain parameters were compared to the deterministic optimization. It was noticed that both geometrical and magnetic properties tolerances greatly impact the machines' performances, where the magnetic properties had a more significant impact on the mean torque. In such a case, robust optimization is essential to find optimal and robust electric motors designs.

M{é}thodologie de dimensionnement par optimisation bay{é}sienne d'une machine synchro-r{é}luctante assist{é}e d'aimants permanents

In this article, three optimization approaches are exploited to improve the performance of a permanent magnet-assisted synchronous reluctance machine: a first optimization using fixed substitution models and two Bayesian optimization approaches based on adaptive substitution models. The results show that Bayesian approaches lead to machines with better performance using the same computation time (same number of finite element simulations). Unlike optimization methodologies based on fixed substitution models, Bayesian approaches provide solutions directly based on finite element simulations and, therefore, do not require verification.

Robust design optimization taking into account manufacturing uncertainties of a permanent magnet assisted synchronous reluctance motor

In this paper, deterministic and robust design optimizations of a permanent magnet assisted synchronous reluctance machine were performed to increase its mean torque while reducing torque ripple. These optimizations were carried out using a surrogate model based on 2-D finite element simulations. The results of the robust optimizations, which considered manufacturing uncertainties, were compared to the deterministic optimization. The robust designs have shown not only good mean torque and torque ripple performances, but they have also shown improved robustness against design parameters uncertainties.
