Moog Components Group has been
designing and producing specialized high
technology and utility electromechanical
actuators for over 20 years. Total in-house
design, engineering and manufacturing
expertise for these products.
Rotary Servo Actuators
Rotary brush motor servo actuators
utilize brush-type DC motors using both
Alnico and rare earth magnets. These
units have been designed with separate
or imbedded analog or digital ampliers,
spur gearing and potentiometers as
feedback devices. Typical applications
include UAV, RPV, target drones and utility
aircraft applications.
