项目摘要
Title: CAREER: Exact Actuation of Magnetic Field Forces Across All Degrees of Freedom in Electric Motors Abstract:Non-technical description: Electric motors are responsible for transporting the world's supply of fresh water, heating and cooling homes and offices, driving critical medical and surgical equipment, and, increasingly, operating transportation systems. The efficiency of this technology is vital in enabling energy sustainability and reducing humanity's carbon footprint. Conventional electric motors rely on bearings to support their shafts. Unfortunately, these bearings have critical lifetime, reliability, and efficiency shortcomings that limit the electrification of transportation systems, the utilization of renewable generation technologies, and the efficiency of fluid handling infrastructure. This project will investigate a new type of motor that does not use bearings. The new bearingless motors will utilize electric current to create controllable magnetic forces that function as set of bearings. The new motors will look and behave in fundamentally different ways that will enable new, extremely efficient, and ultra-reliable systems. This project targets a 9% reduction in US electric energy consumption by enabling new concepts in compressor systems, electrified transportation, renewable energy generation, and energy storage. To translate these research outcomes into the real world, the project incorporates engagement of both the technical community and general public. Beyond the research outcomes, the team's outreach activities will facilitate development of the diverse STEM workforce needed to maintain US leadership in electromechanical power conversion. The team will develop interactive public exhibits of motor and levitation technology and host STEM-enriched experiences aimed at increasing interest and participation in STEM opportunities for middle and high school females and youth from rural, economically disadvantaged regions.Technical Description: The objective of this research is to overcome fundamental challenges of both conventional motor bearings and magnetic bearings. While today's electric motors utilize and control only one degree of freedom (rotation) this project will develop a new generation of electric motors that are precisely actuated in all six degrees of freedom. These new motors will utilize magnetic field forces that are already present within the motor to create a completely bearingless motor that levitates its own shaft. Modelling, control, and design techniques will be developed to unify the science of electric motors and magnetic levitation. The project will use analytic and numeric modeling approaches to create a framework that models the normal and tangential magnetic stresses on the rotor's surface. This framework will be used to determine the required stator currents needed to produce exact force and torque vectors on the motor's shaft. The project will research optimal design of these new motors and test prototypes to validate this new science. The team will develop the science of bearingless motors for both high speed motor systems (industrial compressors and power grid flywheel energy storage) and low speed motor systems (large diameter, rim-driven motors for flight electrification). The outcomes of the research will be disseminated through the standard channels of academic research (presentations and papers) as well as through the construction of a portable bearingless motor prototype that will be exhibited in public demonstrations, conferences, and visits to research institutes. The team will also develop open source, interactive laboratory electronics kits to demonstrate the principles of magnetic levitation and electromechanical power conversion that will be promoted to allow youth to develop county fair exhibits, lifelong learners to explore electromechanical principles, and teachers to adapt the material for their curriculum.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.
摘要:非技术描述:电动马达负责输送世界各地的淡水、供暖和制冷家庭和办公室,驱动关键的医疗和外科设备,并越来越多地操作运输系统。这项技术的效率对于实现能源可持续性和减少人类的碳足迹至关重要。传统的电机依靠轴承来支撑它们的轴。不幸的是,这些轴承存在严重的寿命、可靠性和效率缺陷,限制了运输系统的电气化、可再生发电技术的利用以及流体处理基础设施的效率。这个项目将研究一种不使用轴承的新型电机。新的无轴承电机将利用电流产生可控的磁力,作为一组轴承发挥作用。新马达的外观和行为将完全不同,这将使新的、极其高效和超可靠的系统成为可能。该项目的目标是通过在压缩机系统、电气化交通、可再生能源发电和能源储存方面启用新概念,将美国的电力消耗降低9%。为了将这些研究成果转化为现实世界,该项目包括技术社区和普通公众的参与。除了研究成果,该团队的外展活动还将促进多样化的STEM劳动力的发展,这是保持美国在机电动力转换领域的领导地位所必需的。该团队将开发电机和悬浮技术的互动公共展品,并主办STEM丰富的经验,旨在增加初中和高中女性和来自农村经济贫困地区的青年对STEM机会的兴趣和参与。技术描述:本研究的目标是克服传统电机轴承和磁轴承的根本挑战。虽然今天的电动马达只利用和控制一个自由度(旋转),但该项目将开发新一代电动马达,在所有六个自由度中精确驱动。这些新型马达将利用马达内部已有的磁场力来创造一种完全无轴承的马达,使其悬浮在自己的轴上。将开发建模、控制和设计技术,以统一电机和磁悬浮的科学。该项目将使用解析和数值建模方法来创建一个框架,对转子表面上的法向和切向磁应力进行建模。该框架将用于确定在电机轴上产生精确力和扭矩矢量所需的定子电流。该项目将研究这些新电机的优化设计,并测试原型以验证这一新科学。该团队将为高速电机系统(工业压缩机和电网飞轮储能)和低速电机系统(用于飞行电气化的大直径轮缘驱动电机)开发无轴承电机的科学。研究成果将通过学术研究的标准渠道(演讲和论文)以及通过建造便携式无轴承电机原型来传播,该原型将在公开演示、会议和访问研究机构时展出。该团队还将开发开源、互动的实验室电子套件,以演示磁悬浮和机电动力转换的原理,并将推广这些原理,让年轻人开发县展会展品,让终身学习者探索机电原理,让教师根据课程改编材料。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。
