传统上，采用无源元件的汽车悬架设计是抓地力、承载力和乘客舒适度这三个相互冲突的需求之间的折衷方案。基于线性电磁电机的主动悬架具有优越的可控性和带宽，可以在车辆底盘和车轮之间提供冲击载荷隔离，因此具有巨大的潜力。它还能够回收被动系统减震器中消耗的能量，从而形成更加节能的悬架系统。本文从性能优化、采用实心定子铁芯实现低成本生产及其对推力的影响以及退磁风险评估等方面介绍了用于主动悬架的高力密度管状永磁（PM）电机设计的相关问题。
Traditionally, automotive suspension designs with passive components have been a compromise between the three conflicting demands of road holding, load carrying, and passenger comfort. Linear electromagnetic motor-based active suspension has superior controllability and bandwidth, provides shock load isolation between the vehicle chassis and wheel, and, therefore, has great potential. It also has the ability to recover energy that is dissipated in the shock absorber in the passive systems and results in a much more energy-efficient suspension system. This paper describes the issues pertinent to the design of a high force density tubular permanent-magnet (PM) motor for active suspension in terms of performance optimization, the use of a solid stator core for low-cost production and its impact on thrust force, and the assessment of demagnetization risk.
