Extreme Power Density & Reliability
For Aerospace Applications.


The R-Series actuators from Ultra Motion leverage years of heritage in high reliability actuator design for aerospace/spaceflight applications. Using Ultra Motion’s flight proven, patented Phase Index absolute position sensor, the R-Series provides high resolution absolute position feedback in the most extreme environments and with uncontested mass, economy, and power density.

R-Series actuators are the perfect solution for new-space and aerospace applications such as thrust vector control, throttle control, and control surface manipulation, or applications that demand the highest power density and reliability available.
