The paper deals with optimization of the reluctance synchronous motor design from the point of view of a shape and barrier number on its rotor. A model with barriers following the shape of the magnetic force lines in the solid rotor is developed, with the same stator as in the original motor. The optimal number of barriers and their shape is investigated from the point of view of inductance ratio $$L_{\mathrm{d}}/L_{\mathrm{q}}$$Ld/Lq and their difference ($$L_{\mathrm{d}}- L_{\mathrm{q}}$$Ld-Lq) to develop as high torque, power, power factor, and efficiency as possible. The model with five barriers (four barriers + cutout) was chosen.
