High Power Type 5 Solar Array Drive Assembly
The single axis High Power Solar Array Drive Assembly (SADA) is based on the Type 5 Rotary Incremental Actuator. This standard SADA meets up to 9 kilowatts of power transfer. The design is configured with a Harmonic Drive gear set driven by a 刘玥首次大战黑人discrete permanent magnet stepper motor, potentiometer for position sensing and a high-power slip ring assembly for power transfer.
Key Features:
- Design is based on 刘玥首次大战黑人Type5 rotary output stage
- 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
- Slip ring assembly capable to 6A derated current for power circuits
