the design of electric machines using the combined algorithm of topology and shape optimization to eliminate the problem of impractical model and distortion of the optimized model

The conventional topology optimization (to) algorithm for an electric machine has a critical problem as the derivation of the impractical model to manufacture. in the case of a conventional step optimization, such as shape optimization (so) after to, the optimized model by to is seriously distorted. to solve these problems, a hybrid optimization algorithm that conducts so and to simultaneously with the pre-processing and the post-processing is proposed in this paper.
