MoogLinear 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.
The Cryogenic Fine Positioning Actuator product is designed to produce very small linear output steps using conventional actuator technology.聽
