Integrated Motion Assembly Case
Challenge: Customer needed a complete azimuth drive assembly that supports a 900 lb cruise missile defense radar under a tethered balloon. The assembly must support the transfer of power and data and control the radar in the azimuth axis.
Solution: Moog designed and built the azimuth drive assembly that integrates power and data slip rings, two-channel fiber optic rotary joint, direct drive motor, resolver and motion controller in a specially designed housing with bearings. This assembly is designed to control a 900 lbm, 300,000 lb-in2 suspended load between rest and 30 RPM.
