SBIR Phase I: High Power Density, High Efficiency Actuation for Robotic Applications

这项小企业创新研究第一阶段的研究提案将展示一系列利用并联磁路（PMC）技术的高效率和高功率密度致动器。这种磁力控制技术将适用于任何电磁设备。与“传统”电磁电机和执行器不同，它们使用受最强大的单个磁铁元件力限制的串联磁路，PMC将来自多个永磁体和场线圈的磁通移动到一个连贯的和可加的几何形状中，极大地提高了效率和功率密度。更广泛的影响将是，除了效率是同等标准电机的4到6倍，产生至少4倍的扭矩外，PMC执行器还允许更大的连续扭矩，比同类执行器更轻，不需要主动液体冷却，并且高度可靠，降低了维护成本。这种致动器技术有可能对机器人、传统汽车、混合动力汽车或电动汽车产生重大影响。

This Small Business Innovation Research Phase I research proposal will demonstrate a family of high efficiency and high power density actuators utilizing Parallel Magnetic Circuit (PMC) technology. This magnetic force control technology will be 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 broader impact will be that in addition to being four to six times as efficient and producing a minimum of four times as much torque as an equivalent standard motor, PMC actuators also allow greater continuous torque, are lighter to comparable actuators, require no active liquid cooling, and are highly reliable with reduced maintenance costs. This actuator technology has the potential to have a significant impact in robotics, conventional vehicles, and hybrid-electric, or electric vehicles.
