The Moog Type HT-1 Rotary Incremental Actuator is a new addition to the rotary actuator product line. It is a compact, closely integrated coaxial design composed of a small size permanent magnet stepper motor driving the output stage through a gear transmission consisting of a larger size harmonic drive. The actuator provides relatively high holding and running torque for its size. This actuator is optimized for low weight and relatively high torsional stiffness. Co-axial nesting of the motor and transmission drive elements gives the unit a small profile geometry. Nested new technology using coarse and fine potentiometers provide high resolution, telemetry with noise-free operation.
Moog is a proven leader in components, subsystems, and systems for spacecraft of all sizes, from smallsats to GEO spacecraft. Moog has been successfully providing spacecraft controls, inspace propulsion, and major subsystems for science, military, and commercial operations for more than 60 years.
