Introducing New R-Series Actuators

Designed for the demanding shock and vibration environments of the new-space industry, the R-Series actuators from Ultra Motion leverage years of heritage in high reliability actuator design for 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 […]

Thrust Vector Control with Ultra Motion’s B1 Actuators

Ultra Motion’s B1 series uses best-in-class motors and robust mechanics to provide extremely high power density linear actuators. The B1 can provide continuous forces up to 500 lbf with speeds up to 2.75 in/s, or 200 lbf continuous with speeds up to 8.0 in/s. The low inertia motors offer excellent performance for applications requiring high […]

Vacuum Linear Actuators

High Force Capability Vacuum Linear Actuators

Over 20 years of linear motion experience has culminated in the development of a design and assembly process that produces a high performing linear actuator rated for forces up to 500 lbf and operation within vacuums to 10^-6 Torr. Our vacuum actuators make use of special lubricants, plastics, and motors, as well as design features […]

Throttle Valve Actuators

Using a triple redundant version of Ultra Motion’s Phase Index absolute position sensing technology, these actuators provide high accuracy, high bandwidth control over propellant flow in a manned spaceflight application. In order to comply with NASA-STD-5017 requirements, these actuators were designed to provide utmost reliability across extreme environmental conditions (shock, vibe, saltwater submergence, and a […]

The Industrial Servo Cylinder, Series A2

The A2 Industrial Servo Cylinder is designed to excel in industrial/harsh environments where exposure to dirt, liquids, washdown, or other demanding conditions may be expected. The A2 Industrial Servo Cylinder makes use of the same robust control electronics and drive components as the A1, but includes several upgrades to increase its environmental ruggedness. Upgrades include: […]

Power Supply Unit

New Product: Ultra Motion Power Supply Unit

The Ultra Motion Power Supply Unit is an unregulated AC to DC supply designed specifically for DC motion control applications, including ServoCylinder, and is perfectly suited to most 36V DC motor applications. A Power Supply Unit (PSU) used in DC motion control applications must be sufficiently robust to provide the large bursts of current typical […]
