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 […]

High Force Capability Vacuum Linear Actuators

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 […]

Servo Cylinders in Parallel Mechanism Space Structures Robot


Six Standard (A1) Servo Cylinders were used on the NINJAR robot to help NASA meet its goals for robotic in-space assembly and manufacturing. The Servo Cylinders are mounted in a parallel kinematic arrangement to provide multiple degrees of freedom and high stiffness to the structure. The parallel manipulator allows for complete control over the structure’s […]

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

A2 home news feed

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: […]

New Product: Ultra Motion Power Supply Unit

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 […]

A1 Servo Cylinder RC PWM (1-2 ms pulse) Demonstration

Servo Cylinder 1-2 MS Pulse

RC PWM (1 to 2 ms pulse) is a common protocol used by professional autopilots for high end UAV platforms. The Servo Cylinder actuator will accept 50 Hz and up to 333 Hz RC PWM natively through the optically isolated digital inputs. The Servo Cylinder provides high reliability actuation in a rugged package and makes […]
