In the design of modern, high-performance switched reluctance machines, the highly restrictive sets of constraints and requirements severely limit the number of feasible solutions. In order to improve the chances of attaining a successful design, this work proposes a novel and fully analytical approach to the preliminary design analysis. Initially, the correct number of independent design variables is identified. Subsequently, constraints and requirements are introduced one by one, in order to progressively discard all of the unfeasible candidates. At the end of this process, the actual design space is attained, whose main characteristic is to be populated only by feasible candidates. A design case study shows how the proposed methodology allows: 1) to verify the design feasibility; 2) to reduce the number of candidates by orders of magnitude; and 3) to gain useful insight into the design problem and thus select the most convenient strategy to finalize it. As a result, a highly effective design process is attained, so that considerable computational resources can be saved.

开关磁阻电机初步设计分析的实际设计空间方法

在现代高性能开关磁阻电机的设计中，高度限制性的约束和要求严重限制了可行解决方案的数量。为了提高获得成功设计的机会，这项工作提出了一种新颖且全面的初步设计分析方法。最初，确定了正确数量的独立设计变量。随后，约束和要求被一一引入，以逐步丢弃所有不可行的候选者。在此过程结束时，获得实际设计空间，其主要特征是仅由可行的候选者填充。设计案例研究显示了所提议的方法如何允许：1) 验证设计可行性；2）按数量级减少候选数量；3) 获得对设计问题的有用洞察，从而选择最方便的策略来完成它。结果，实现了高效的设计过程，从而可以节省大量的计算资源。
