1. An electro-mechanical actuator coupled to a first mounting point and a second mounting point, the electro-mechanical actuator comprising:
a screw;
a first nut on the screw, wherein the first nut is coupled to the first mounting point;
a first inverted nut coupled to the first nut;
a sensor assembly configured to generate signals indicative of (a) the position of the first nut on the screw or (b) changes in the position of the first nut on the screw;
a first motor configured to rotate the first nut about a screw axis of the screw; and
a backup motor configured to rotate the first nut about the screw axis of the screw,
wherein a controller module is configured to control the first motor or the backup motor based on the signals generated by the sensor assembly.
