Ultra Fine Angle Rotary Incremental Actuators
Along with the standard Type 3 and Type 5, the Moog Type3-EF and Type 5-EF Rotary Incremental Actuators are new additions to the rotary incremental actuator lines. The design is based on a recently developed ultra-fine (sub-degree) step angle permanent magnet stepper motors which in combination with the standard harmonic drive gear reducers produces extra fine output step resolution. The new line of actuators offers quiet operation, low weight, zero-backlash, and high output torsional stiffness. All electrical elements, such as motors and position sensors, can be redundant with little or no change in actuator envelope.
Key Features:
- Ultra-fine proprietary permanent magnet stepper motors
- Very fine output resolution provides fine pointing
- Quiet operation
- Low weight
- Zero backlash
- High torsional and moment stiffness
