Abstract
A linear actuator is provided. The linear actuator includes a rotor assembly including a rotor and a lead screw. The lead screw is rotationally coupled to the rotor for rotation therewith. The linear actuator further includes a stator assembly configured to selectively rotate the rotor in a desired direction, and a body assembly having a shaft and a shaft tube. The shaft is keyed to the shaft tube and prevented from rotating with the rotor. The shaft includes an inner bore configured to threadably receive the lead screw therein. Selective rotation is configured to displace the shaft between an extended position and a retracted position.
