Linear electrical machines provide a compact and mechanically efficient way of interfacing electrical power and linear motion. A linear electrical drive consists of an electrical machine, a power converter, a motion control algorithm, a power flow controller and mechanical integration. Within electric propulsion, linear electrical drives have applications in free piston engines, aerospace actuation, mag-lev and electric steering. Outside of propulsion, they are commonly found in industrial process actuation and considered in renewable energy applications.Although the electromagnetics are common with their rotatory counterpart, the reciprocating nature of linear drives poses unique challenges to the electrical machine and power converter, resulting in pulsating electrical power and unbalanced magnetic forces. High force density, high efficiency, low cost, robust and fault tolerance are all desirable qualities, and the most appropriate design is often a compromise between these in terms of impact on overall system cost.In this project overall power density (kW/kg) of linear electrical drives will be investigated. By integrating models of active mass, support structures and power electronic components, a scalable linear electric drive will be developed against a typical propulsion specification.

线性电机提供了一种紧凑且机械高效的方式来连接电力和线性运动。线性电力驱动器由电机、功率转换器、运动控制算法、功率流控制器和机械集成组成。在电力推进领域，线性电力驱动器可应用于自由活塞发动机、航空航天驱动、磁悬浮和电动转向。除了推进之外，它们还常见于工业过程驱动中，并在可再生能源应用中得到考虑。尽管电磁学与旋转驱动器很常见，但线性驱动器的往复性质给电机和功率转换器带来了独特的挑战，导致脉动电力和不平衡磁力。高力密度、高效率、低成本、坚固耐用和容错能力都是理想的品质，而最合适的设计通常是在对总体系统成本的影响方面进行折衷。在该项目中，将研究线性电气驱动器的总体功率密度（kW/kg）。通过集成主动质量、支撑结构和电力电子元件的模型，将根据典型的推进规格开发可扩展的线性电力驱动器。
