This SBIR Phase I research proposal will analyze, develop, and demonstrate a novel, optimized, high power density and high efficiency electric motor technology capable of operating at high speeds using Parallel Magnetic Circuit (PMC) technology. PMC technology is a breakthrough magnetic force control technology that is applicable to any electromagnetic device. Unlike ?conventional? electro-magnetic motors and actuators, which use series magnetic circuits limited by the force of the most powerful single magnet element, PMC moves flux from multiple permanent magnets and field coils into a coherent and additive geometry - dramatically increasing both efficiency and power density. The proposed motor will have efficiency greater than 90 percent over a broad range of operating speeds with peak efficiency greater than 97 percent, operate at speeds in excess of 20,000 rpm, cost less than comparable existing permanent magnet motors, and require no active liquid cooling when operating within the designed parameters. These power generators have significant quantitative and qualitative advantages over the incumbent motors being used in the current variable speed applications. Their smaller size and ability to operate more efficiently over a wider range of operating speeds, as well as their ease of integration, installation, and projected reliability, would greatly increase electric motor viability in the commercial market. This would significantly increase the viability of electric drive trains and speed the adoption of efficient and environmentally sustainable electric vehicles.

该SBIR第一阶段研究计划将分析、开发和演示一种新型的、优化的、高功率密度和高效率的电动机技术，该技术能够使用并联磁路（PMC）技术在高速下运行。PMC技术是一种突破性的磁力控制技术，适用于任何电磁设备。与传统的?电磁电机和致动器使用由最强大的单个磁铁元件的力限制的串联磁路，PMC将来自多个永磁体和场线圈的磁通移动到连贯和可加的几何形状中-显着提高了效率和功率密度。提议的电机在广泛的运行速度范围内效率大于90%，峰值效率大于97%，运行速度超过20,000 rpm，成本低于现有的同类永磁电机，并且在设计参数内运行时不需要主动液体冷却。这些发电机在数量和质量上都比目前在变速应用中使用的现有电机有显著的优势。它们更小的尺寸和更大的运行速度范围内更有效的运行能力，以及它们易于集成、安装和预期的可靠性，将大大提高电动机在商业市场上的可行性。这将大大提高电动传动系统的可行性，并加快采用高效、环保的可持续电动汽车。
