High Power Type 5-TC Solar Array Drive Assembly聽
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 10 kilowatts of power transfer. The design is configured with a Harmonic Drive gear set driven by a Moogdiscrete permanent magnet stepper motor, potentiometer for position sensing and a high-power Twist Capsule assembly for power transfer.
Key Features:
- Design is based on MoogType5 rotary output stage
- Integrated twist capsule assembly for power and data transfer
- Integrated potentiometer position feedback
- Low weight
- Zero backlash
- Twist capsule capable of up to 10Kw power transfer
