Linear Actuators

Moog Linear Actuators use a ball screw or leadscrew to translate the rotary motion of 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 stepper motor design. 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.
