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.

自1940年以来，2023年就目睹了地球上最热的日子，强调了抵抗气候变化和过量碳排放的紧迫性。在此任务中，电动机和发电机或集体电机（EMS）起着关键作用。通过EMS产生了超过90％的全球电力，其中45％变成了机械工作。 EMS是电动汽车（EV），风能产生和各种工业过程的核心，推动了这些基本应用的前进。为了突破EM性能边界，探索多物理设计空间至关重要，该设计空间包括各种物理学科的相互作用，例如电动力学，传热和结构力学。多物理设计空间受EM拓扑的限制，即EMS组成部分的布置，包括钢，铜，磁铁等。一个自然的问题是：这些构造部分的最佳布置是什么？拟议的研究被毒死了，可以系统地回答这个基本问题，并加快对高性能和高度可持续性EMS的探索。与研究的同时，PI的教育目标是系统地培养潜水员多物理学设计师，包括那些人数不足的人。 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 topology are often conceived by designers and the concept relies on their intuition,导致零星揭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，该职业项目的总体目标是开拓新的设计范式 - 多物理综合，该范围综合，通过使用紧张分析来实现对EMS多物理设计空间的指导探索。为了实现这一目标，计划了三个研究推力。首先，由电动力学控制并在高维空间中表达的原始EMS将被用作推导新拓扑的起点。其次，EMS的高维模型将体现在3D空间中，以进行性能评估和优化。第三，前两个推力中的方法将被推广，以纳入电子设备以外的物理学并实现多物理合成。在所有三个推力中，都将应用数学（几何）和理论物理学（相对论）的张力分析。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
