In this article, a new multi-rod linear actuator is presented. This actuator has been developed for high thrust density and wide mechanical band pass applications. The multi-airgap concept will first be illustrated and explained. Its advantages will be highlighted thanks to finite element method optimizations. Next, the multi-rod prototype technology will be discussed. Lastly, experimental measurements for prototype forces will be provided.
