Moog Linear Actuators use a ball screw or leadscrew to translate the rotary motion of a brushless DC or a stepper motor to linear output motion. The torque transmitted to the output stage is amplified through a gear transmission. The driving motor is a 3-phase, multi-pole, permanent magnet, brushless DC, or stepper motor design. Position is monitored through a linear potentiometer integrated into each unit. The linear actuators have integrated non-jamming stops at the full extend and full-retract positions. Thermistors, heaters, or thermostats can easily be incorporated into these designs.
These Linear Actuators use a ball screw to translate the rotary motion of a brushless DC motor to linear output motion.
The Cryogenic Fine Positioning Actuator product is designed to produce very small linear output steps using conventional actuator technology.
