This article proposes a continuum-sensitivity-based method to obtain the optimal design for an interior permanent magnet synchronous motor (IPMSM). Compared with the finite difference method, the continuum sensitivity analysis shortens the computation time significantly when there are numerous design variables. We combine the continuum sensitivity with the shape constraint so that both the shape and the size can be optimized simultaneously and within a short time. This proposed design optimization method is applied to IPMSM rotor design, and its feasibility is verified. The proposed method is expected to be effective for various design problems that require the shape and the size to be optimized simultaneously.

基于连续体灵敏度的永磁体形状约束内置式永磁同步电机优化


本文提出了一种基于连续体灵敏度的方法来获得内置式永磁同步电机 (IPMSM) 的优化设计。与有限差分法相比，当设计变量较多时，连续灵敏度分析大大缩短了计算时间。我们将连续体敏感性与形状约束相结合，以便可以在短时间内同时优化形状和尺寸。将所提出的设计优化方法应用于IPMSM转子设计，并验证了其可行性。该方法有望有效解决需要同时优化形状和尺寸的各种设计问题。
