What Ultra Motion does

Ultra Motion LLC is a privately held US-based manufacturer founded in 1994 and headquartered in Cutchogue, New York, specializing in precision electromechanical servo actuators for extreme environments. The company designs and builds linear actuators, rotary actuators, and servo cylinders rated for deep-subsea operation beyond 6,000 meters, space-grade vacuum (1×10⁻⁶ Torr), cryogenic temperatures down to -181°C, and high shock/vibration conditions. Its product portfolio centers on five core series — U-Series (underwater), L-Series (linear servo), T-Series (rotary servo), R-Series (aerospace power-dense), and A-Series (modular Servo Cylinder with A1/A2/AU/AM variants) — plus a redundant L2D variant, legacy B/D/I series, and supporting power supplies.

The company's underlying technology platform combines integrated brushless DC (BLDC) control electronics, multi-protocol communication (CAN 2.0B, RS-485, RS-422, RC PWM, 4-20 mA), and the proprietary patented Phase Index® contactless absolute position sensor. The Phase Index® technology provides self-calibrating, high-resolution absolute position feedback without homing routines or backup power, a capability marketed as exclusive to Ultra Motion. Strategic component partnerships with Faulhaber (BLDC motors) and Embention (autopilot integration) extend the platform's reach into autonomous systems.

Revenue is generated primarily through direct hardware sales of standard catalog products (available via an online configurator) and custom-engineered actuators for mission-specific requirements. The company sells directly to enterprise, government, and research customers across aerospace, defense, underwater/marine, uncrewed vehicles, industrial automation, medical, and science/research verticals. Go-to-market relies on technical content marketing, an engineering-led sales motion, and tradeshow presence at XPONENTIAL and ATX East. Named customers include NASA, NIST, Johns Hopkins APL, Brookhaven/Sandia/Oak Ridge national laboratories, Hermeus, Phenix UAS, Exosonic, Honeybee Robotics, and North Sea Systems, with applications spanning the NASA Dragonfly Titan mission, hypersonic engine hot-fire testing, lunar spectral irradiance calibration, and subsea cable installation.
