Type 2 Solar Array Drive Assembly
The single axis Type 2 Solar Array Drive Assembly (SADA) is based on the Type 2 Rotary Incremental Actuator. The standard actuator has varied over many applications to meet mission requirements. Generally, the items that tend to vary are interface parameters and power transfer requirements. All the represented Type 2 SADA designs are configured with harmonic drive gear sets, potentiometers for position sensing and a slip ring assembly for power and signal transfer. As with all Moog mechanisms, a variety of design options are available. Custom power transfer requirements are easily accommodated upon request. The designs represented on this data sheet are qualified and provide an option that has cost and schedule benefits. The Type 2 SADA easily interfaces with the Moog 2 or 4 channel Electronic Control Unit for a complete system solution. Contact Moog engineering for assistance with your application.
Key Features:
- Design is based on Moog Type2 rotary actuator
- Integrated slip ring assembly for power and data transfer is mounted on the rear of the actuator
- Integrated potentiometer position feedback
- Low weight
- Zero backlash
- Optimized for low power consumption
