Magneto-Mechanical Topology Optimization With Generalized Optimality Criteria

In this article, the design of a synchronous reluctance motor (SynRM) is subjected to a multiphysical topology optimization (TO) using the generalized optimality criteria (GOC) method. To ensure the structural integrity of the rotor, a two-step magneto-mechanical optimization approach is employed. The objective functions, focusing on magnetic and mechanical aspects, are formulated by considering the magnetic energies obtained from d- and q-axis stator currents, as well as the mechanical compliance. The gradients of these objective functions are computed using the adjoint variable method (AVM).
