    Abstract

    In recent years the numerical design optimization of magnetic devices has been the focus of interest of many engineers. In designing the practical devices such as induction motors, we have to estimate many kinds of objective physical quantities in the optimization process: e.g. magnetic flux, eddy current, torque, etc. This makes it difficult to obtain the effective solution that achieves the high device performance boosts within an acceptable CPU time. Thus, some contrivances to the practical design optimization are indispensable according to the device characteristics. In this paper, with this background, we propose an effective approach to the design optimization of rotating machinery by using the numerical analysis combined with the analytical design methodology and physical considerations. To verify the proposed approach, some numerical results, i.e., the shape optimization of ventilation holes in an induction motor, are also presented. In the numerical example, our goal is to widen the ventilation hole area without making the influence of the rotor-yoke saturation more serious.
