In this paper, an approach to arrive at the optimal design variables to maximize the torque density of an axial multi-layer synchronous reluctance motor that can be used as an electric actuator is presented. Considering the flux saturation phenomenon of the core along the primary path of the d-/q-axis of the magnetic flux is an important design criterion in designing the synchronous reluctance motor to improve the torque density and to increase the ratio and the difference between Ld and Lq. Change in the thickness of the magnetic flux barrier has the greatest effect on the magnetic flux path and its characteristics. Dependence on the presence or absence of a rotor core rib, which causes magnetic saturation, was analyzed by calculating the inductance. Results are demonstrated through the finite-element analysis simulation and an experiment.
