For this paper, the possibility of using grain-oriented electric steel for the stator lamination in a double rotor fractional-slot concentrated-wound permanent magnet synchronous motor it was studied using FEM simulations. The results were compared with the ones of the non-oriented electric steel machine having two different stator lamination topologies. The purpose of this study was to estimate the influence of the stator yoke discharge for the proposed structure and to check the possibility of compensating some of its negative effects by using grain-oriented electric steel for stator lamination. The proposed solution gives the advantage of a modular construction of the stator lamination which simplifies the fabrication technology and reduces the production costs, at the same time, without major impact over the machines performances.
