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