The Micro3 rotary incremental actuator is a compact, closely integrated design made up of two key elements: a rotary actuator and a standard Type 3 speed reducer and output flange. The motor is a small angle permanent magnet stepper with relatively high holding torque. The multi-stage speed reducer offers a large reduction ratio, low weight, low power consumption, zero backlash and high torsional stiffness. Co-axial nesting of the motor and transmission drive elements gives the unit low profile geometry. The actuator can be made available in two and three phase motors and has the identical mounting features of the Moog standard Type3 line of Rotary Actuators.
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.
