What WE DID:
- Design
- Development of unit and derivative products
The Environments:
- Air
- Land
- Sea
- Space
The challenge requirements:
- Three-phase motor windings
- Rated for an altitude of 400,000 feet with a high duty cycle
- No-load speed greater than 15,000 RPM and stall torque greater than 80 in-lbs
- Max temperature rating of 155 Degrees C
- Winding voltage at 150 VDC with a continuous current capability of 50 Amps and a peak
The Solution:
- Vacuum encapsulated windings for the three-phase motor windings and the resolver commutation
- 2.5” in diameter and approximately 8.2” long
- Temperature sensing thermistor embedded in the winding end turns for real-time temperature data during flight
- Two D38999 connectors isolated the high-power motor leads from the signal leads associated with the resolver commutation and thermal sensor
- Capability of 100 Amps
APPLications:
- Primary and secondary flight control systems (FCS)
- SpaceShip2 (SS2)
- WhiteKnight2 (WK2), horizontal stabilizer trim actuation
- High attitude long endurance unmanned air vehicles
- Fin control systems
