Optimal design of electric machine based on FEM (Finite Element Method) calls for much longer computation time. In this paper, optimal design is implemented with randomly guided MADS (Mesh Adaptive Direct Search) and FEA (Finite Element Analysis) to compensate the excessive computation time. In addition, the proposed MADS coupled with FEA has been forwarded to Optimal design of Interior PM Synchronous Machine for Maximum Torque Per Ampere (MTPA). In particular, Randomly guided MADS has contributed to reducing the excessive computing time for the optimization process when compared with conventional MADS.
