Actuators & Servoactuators

Linear Actuators for Spacecraft

Our Linear Actuators use a ball screw to translate the rotary motion of a brushless DC motor to linear output motion. The torque transmitted to the ball screw is amplified through a helical gear transmission. Each motor is a 3-phase, multi-pole, permanent magnet, brushless DC design. Position is monitored through a linear potentiometer integrated into each unit. The unit shown has no-jamming stops at the full extend and full-retract positions. Thermistors, heaters, and thermostats can easily be incorporated into these designs.

The product mentioned is only a sample of our linear actuator offerings. For more information, please see our Spacecraft Mechanisms catalog or contact us for product details and customized solutions.
