Summary:This paper proposes a novel optimization method, Boolean geometry projection method, for the determination of permanent magnet configuration in interior permanent magnet motors. In the proposed optimization, the magnet configurations are freely modified without the upper and lower limits of shape parameters that have to be carefully determined by users. It is shown that the proposed method leads to the torque performance better than that obtained by conventional approaches.
