Component Focus: Internal Desiccant
All of the dynamic shaft seal design efforts taken by Ultra Motion will minimize the amount of liquid ingress into the actuator enclosure, but 100% moisture exclusion is not feasible. For this reason, the A2 and AM Servo Cylinders include a custom injection molded desiccant block in close proximity to the control electronics and BLDC stator to adsorb moisture […]
Ultra Motion Actuators Go Offshore On Subsea Cable Installation Carriage
Great to see our U1 Series subsea linear actuator being used in North Sea Systems’ CableFish. The system provides subsea cable installers with continuous video and mapping of the product as it contacts the seabed. Our actuator enables the survey carriage to be attached and removed from the cable without any manual intervention – thereby […]
Servo Cylinder Tests Future Interplanetary Rotorcraft in Simulated Titan Atmosphere
Dragonfly is a rotorcraft lander being designed by the Johns Hopkins Applied Physics Laboratory in support of NASA’s New Frontiers program. The Dragonfly dual-quadcopter will be sent to explore Saturn’s moon, Titan, and to take a variety of in-flight atmospheric and surface measurements. Titan’s dense atmosphere and low gravity make it an ideal candidate for […]
New CAN Protocol For Servo Cylinder
Ultra Motion has released a new general-purpose CAN protocol for the Servo Cylinder that can be configured for use in a wide range of systems from commercial autopilots or J1939 systems to python test setups or microcontrollers. This simple to implement protocol leverages the networkability and extremely reliable hardware layers of CAN to create robust motion control […]
Ultra Motion Actuators Help Measure The Moon At 70,000 Feet
Photo Credit: Ken Ulrich, NASA The airborne lunar spectral irradiance mission (Air-LUSI) is a partnership between NASA and NIST to create SI-traceable measurements of lunar spectral irradiance in an effort to improve the measurements of Earth observing satellites. These satellites monitor the weather, vegetation, ocean currents, pollution, and more. Using the light reflected from the […]
A2 Servo Cylinders Provide Nozzle Flap Control On Hypersonic Aircraft Engine
Hermeus is an exciting new company developing a hypersonic aircraft with the goal of revolutionizing commercial flight. Ultra Motion’s A2 Servo Cylinders control the nozzle flaps of their prototype engine during hot-fire testing. The Servo Cylinder’s robust construction ensures reliable operation in the harshest environments and the Phase Index absolute position sensor provides rock-solid feedback […]
