The year 2023 has witnessed the hottest days on Earth since 1940, highlighting the urgency of the fight against climate change and excessive carbon emissions. In this mission, motors and generators, or collectively electric machines (EMs), play a pivotal role. Through EMs, over 90% of global electricity is generated, 45% of which is turned into mechanical work. EMs are at the heart of electric vehicles (EVs), wind energy generation, and various industrial processes, propelling these essential applications forward. To push EM performance boundaries, it is crucial to explore the multiphysics design space, which encompasses the interplay of various physical disciplines, such as electrodynamics, heat transfer, and structural mechanics. The multiphysics design space is confined by EM topologies, i.e., arrangements of constituent parts in EMs including steel, copper, magnets, etc. A natural question to ask is: what are the best arrangements of these constituent parts? The proposed research is poised to systematically answer this fundamental question and accelerate the exploration of high-performance and highly sustainable EMs. Parallel to the research, the PI’s education goal is to systematically foster diverse multiphysics designers, including those who are underrepresented. The PI’s education activities will include constructing a website-based learning platform named TENSOR to create an inclusive multiphysics learning hub, implementing a duality and analogy-based multiphysics education technique for K-12, undergraduate, and graduate students, and offering an open-access new EM design course to the frontier EM workforce.In the existing design paradigm, new EM topologies are often conceived by designers and the conception relies on their intuition, resulting in sporadically revealing new design space and corresponding performance space. To overcome the limitations of this intuition-based design paradigm, the overarching goal of this CAREER project is to pioneer a new design paradigm — multiphysics synthesis which realizes guided exploration of multiphysics design space for EMs using tensorial analysis. To achieve this goal, three research thrusts are planned. First, primitive EMs, governed by electrodynamics and expressed in hyperdimensional space, will be used as starting points to derive new topologies. Second, the hyperdimensional models of EMs will be embodied in the 3D space for performance evaluation and optimization. Third, the methodologies in the first two thrusts will be generalized to incorporate physics beyond electrodynamics and fulfill multiphysics synthesis. In all three thrusts, tensorial analysis originated from mathematics (geometry) and theoretical physics (relativity theory) will be applied.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

2023年见证了自1940年以来地球上最热的几天，突显了应对气候变化和过度碳排放的紧迫性。在这项任务中，电机和发电机，或统称为电机(EM)，发挥着关键作用。通过新兴市场，全球90%以上的电力产生，其中45%转化为机械工作。EMS是电动汽车(EVS)、风能发电和各种工业流程的核心，推动着这些基本应用的发展。为了推动电磁性能的极限，探索多物理设计空间是至关重要的，它包含了各种物理学科的相互作用，如电动力学、传热学和结构力学。多物理设计空间受到EM拓扑的限制，即EM中的组成部分(包括钢、铜、磁铁等)的排列。一个自然的问题是：这些组成部分的最佳排列是什么？这项拟议的研究将系统地回答这一根本问题，并加快探索高性能和高度可持续的新兴市场。与这项研究平行的是，PI的教育目标是系统地培养多样化的多物理设计师，包括那些代表性不足的设计师。PI的教育活动将包括构建一个名为tensor的网站学习平台，以创建一个包容性的多物理学习中心，为K-12、本科生和研究生实施基于二元性和类比的多物理教育技术，并向前沿EM劳动力提供开放访问的新EM设计课程。在现有的设计范式中，新的EM拓扑通常是由设计师构思的，概念依赖于他们的直觉，从而零星地展示新的设计空间和相应的性能空间。为了克服这种基于直觉的设计范式的局限性，这个职业项目的首要目标是开创一种新的设计范式--多物理综合，实现利用张量分析引导探索新兴市场的多物理设计空间。为了实现这一目标，计划进行三项研究推进。首先，由电动力学支配并在超维空间中表示的原始EM将被用作推导新拓扑的起点。其次，将EMS的超维模型体现在3D空间中，用于性能评估和优化。第三，前两个推进中的方法论将被推广到将物理学纳入电动力学之外，并实现多物理综合。在所有三个推力中，将应用源于数学(几何)和理论物理(相对论)的张量分析。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
