Type 1 Solar Array Drive Assembly
The Type 1 solar array drive assembly offers a minimum weight, minimum power solution for positioning solar array panels at the lower end of the size/power spectrum. It is based on the Moog Type 1 rotary incremental actuator. Continuous rotation of the solar array is facilitated by the integration of a slip ring assembly on the output of the actuator, and the rear accessory section of the Type 1 actuator is available for a position feedback device-potentiometer or encoder. Selecting the qualified unit in its existing configuration will have cost and schedule benefits. However, as with all Moog designs, the slip ring assembly is modular. Substitutions and modifications to meet mission requirements are easily implemented. Integration of the actuator with another similar Type 1 actuator will produce a Type 11 biaxial SADA. Typical Type 1 performance specifications are shown in the table below. The unit is driven by the standard Moog Electronic Control Unit.
Key Features:
- Design is based on Moog Type1 rotary actuator
- Integrated slip ring assembly mounted on the output of the actuator
- Integrated potentiometer position feedback
- Low weight
- Zero backlash
- Optimized for low power consumption
