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 ampliers,
spur gearing and potentiometers as
feedback devices. Typical applications
include UAV, RPV, target drones and utility
aircraft applications.
