这个小企业创新研究（SBIR）第一阶段项目将开发一种设计，将电容启动分马力多极交流电机的效率提高33%。结果将为制造商带来显著的优势，通过将电机改造到当前的工业机械中，以显着降低电力消耗和运营成本。该电机还将通过降低运营成本和提高生产率，为新型工业机械制造商提供竞争优势。小型交流电动机的平均效率为60%。涡流和I2R损耗是主要损耗，以热的形式存在。该项目将确定设计的可行性，从而大大减少这些损失，从而将效率提高到80%。该方法将包括开发定义电机的算法，新型转子结构，使用软磁复合材料，优化线圈部分通电的特性，以及由材料科学和建模的进步支持的研究。为了提高工业机械的竞争力，研究的预期结果包括一个工作模型，将满足以下性能指标：效率达到或高于80%；温度上升20℃；信封尺寸缩小50%；与现有标准产品的成本相当。该项目更广泛的（商业）影响可以将小型电机的效率从60%提高到80%，同时降低运营成本和材料，替代可回收材料，并保持当前的制造成本。将效率提高到80%将为美国制造商节省30 - 70亿美元的净现值，并减少5.2-8.6万亿btu的能源使用。它还将使每年的发电量减少4000万至6700万兆瓦时，并消除对9-15个化石燃料电力设施的需求。降低运营成本和提高生产率将大大有利于制造公司、员工和社区。与之竞争的技术只提高了3%的效率，而增加了至少21%的成本。商业化将通过改造和启用新的机器设计来提高制造效率，提高可靠性，降低废热，缩小空间和更快的精度控制。

This Small Business Innovation Research (SBIR) Phase I project will develop a design to increase efficiency of capacitor-start fractional horsepower multi-pole AC motors by 33%. Results will drive significant advantages for manufacturers by retrofitting motors into current industrial machinery to dramatically reduce electricity consumption and operating costs. The motor will also provide competitive advantage to manufacturers of new industrial machinery by reducing operating cost and increasing productivity. The average efficiency of small AC motors is 60%. Eddy currents and I2R losses are the primary losses and are in the form of heat. This project will determine feasibility of a design that dramatically reduces these losses thereby increasing efficiency to 80%. The approach will consist of developing algorithms that define the motor, novel rotor construction, use of soft magnetic composites, optimizing characteristics that leave the coil partially energized, and research supported by advances in material science and modeling. To increase competitiveness of industrial machinery, the anticipated results of research include a working model that will meet the following performance metrics: efficiency at or above 80%; temperature rise of 20 degrees C; envelope size reduced 50%; and comparable cost to standard available products.The broader (commercial) impact from this project could be increased efficiency of small motors from 60% to 80% while reducing operating cost and materials, substituting recyclable materials, and maintaining current manufactured cost. Increasing efficiency to 80% will save American manufacturers $3-$7 billion net present value and reduce energy use by 5.2-8.6 quadrillion BTUs. It will also reduce electricity generation by 40-67 million megawatt-hours per year and eliminate the need for 9-15 fossil fuel electric utilities. Reductions in operating cost and increased productivity will significantly benefit manufacturing companies, employees, and communities. Competing technologies increase efficiency by a mere 3% and increase cost by at least 21%. Commercialization will increase manufacturing productivity by retrofitting and enabling new machine designs that leverage increased efficiency, higher reliability, lower waste heat, smaller space, and faster precision control.
