Development of Optimal Layout Programming for Magnetic Material and Challenge to the Design of Soft Magnetic Composite Motor

磁性材料的优化排样规划是由大规模整数变量组成的。为了解决拓扑优化问题，我开发了基于进化算法的拓扑优化方法，该方法利用多个分辨率网格和操作来限制设计域在改变分辨率水平。我已经将所提出的方法应用于2-D IPM电机模型的磁通屏障设计。由此产生的磁通屏障增强了转矩特性。所提出的方法的扩展到三维磁路设计是剩余的研究问题。

The optimal layout programming for the magnetic material is composed of large scale integer variables. To solve the topology optimization problem, I have developed the evolutionary algorithm-based topology optimization method, which utilizes the several resolution meshes and the operation to restrict the design domain in changing the resolution level. I have applied the proposed method to the flux barrier design of 2-D IPM motor model. The resulting flux barrier enhances the torque characteristics. The extension of proposed method to 3-D magnetic circuit design is the remaining research issue.
