The Type 3 actuator is one of our more popular designs, with hundreds of units delivered and successfully operating in space. The standard design is based on the Moog heritage actuator concept, a compact coaxially nested motor and harmonic drive gear system. The most popular version incorporates a potentiometer for position sensing with a redundant three phase motor. As with all Moog actuator products, incorporating optional equipment based on the application is possible. This flexible design can accommodate hard stops, 2 or 3 phase stepper motors, brushless DC motors, a variety of position sensors, cable management systems or other application-specific options. These actuators are commonly used in Antenna Pointing Mechanism applications. The actuators can be incorporated into a biaxial gimbal configuration to fit any application. Contact Moog application engineers for assistance with actuator selection and design options.
