Abstract

A novel visualization method for interpreting the resultant design from topology optimization (TO) is proposed. We employ a pre-trained deep learning (DL) model to predict the degree of influence of transitions from air to magnetic materials, and build an interpretable linear model to display the visualization result. The proposed method, Design-LIME, is applied for visualizing the impact of effective regions on the torque characteristics of interior permanent magnet synchronous motors (IPMSMs). Compared to conventional visualization methods based on explainable artificial intelligence (XAI), Design-LIME presents accurate and simple visualization results. Furthermore, a novel multistep TO method is proposed. The proposed TO utilizes Design-LIME to efficiently address the electromagnetic and mechanical characteristics of IPMSMs by extracting the effective region of the IPMSM characteristics. The proposed TO method improves search performance by 18.7% when compared with the conventional single-step optimization method. The proposed method enables more efficient motor designs with improved electromagnetic and mechanical performance. The proposed method contributes to the streamlining of the design process not only for motors but also for various electrical devices.

Design- lime：一种基于深度学习的电机设计可解释可视化方法

提出了一种新的可视化方法来解释拓扑优化的结果设计。我们使用预训练的深度学习（DL）模型来预测从空气到磁性材料的转变的影响程度，并建立一个可解释的线性模型来显示可视化结果。提出的Design-LIME方法用于可视化有效区域对内置永磁同步电机转矩特性的影响。与传统的基于可解释人工智能（XAI）的可视化方法相比，Design-LIME的可视化结果准确、简单。在此基础上，提出了一种新的多步TO方法。该算法利用Design-LIME方法，通过提取IPMSM特性的有效区域，有效地解决了IPMSM的电磁和机械特性问题。与传统的单步优化方法相比，该方法的搜索性能提高了18.7%。所提出的方法使更有效的电机设计与改进的电磁和机械性能。该方法不仅简化了电机的设计过程，而且简化了各种电气设备的设计过程。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
