1 Electromechanical Rotary Actuator TYPICAL APPLICATIONS Axis motion control for gimbal and pedestal systems Azimuth, elevation, fold / unfold, leveling control Suitable for airborne and ground based systems Model 25 FEATURES 1,4 lb-in peak torque Rugged design Assembly integrates: - High performance DC brushless motor - Resolver - Planetary gearbox - Power-off brake High output torque per volume or weight Low inductance for maximum dynamics Low mechanical backlash for precise positioning Supports high radial and axial loading BENEFITS Can be operated in limited rotation or full 3 continuous operation Mounting plate and output shaft can be modified for specific applications Use of brushless motor allows for higher peak torque and longer life as compared with a brush-type motor Rugged design and construction allows assembly to be operated under adverse environmental conditions Introducing Moog Components Group Model 25 Rotary Electromechanical Actuator that develops up to 14 lb-in of stall torque with a 48 VDC input at 25 C. It integrates a high performance brushless DC motor with Hall Effect devices, a highly accurate planetary gearbox, commutation resolver and power-off brake. Model 25 is designed to meet challenging environmental conditions, and can operate in both continuous and limited angle motion profiles. The spur gear output shaft can withstand heavy axial and radial forces, allowing the actuator to be adapted to a variety of applications.
