Disclosed herein is an electromechanical actuator which acts as an analog of a fluid operated cylinder. A tubular piston moves along the axis of a fixed outer cylinder. One end of the piston is fitted with a threaded stud to which a clevis or other load attachment device can be attached. The other end of the piston, inside the outer cylinder, is attached to a coaxial drive nut. The drive nut is threaded onto a coaxial lead screw which passes through the drive nut and clears the inside of the piston. The drive nut is notched at a plurality of locations, t...


In an electromechanical actuator for taking the rotational motion of an electric motor and varying the spacing between two actuator ends from a first close disposition to a second spaced disposition; said actuator including an electric motor having a current input and rotating power output; a rotating and threaded lead screw attached for rotation with respect to one of said actuator ends; a drive nut having threads complementary to said lead screw; means for linking said drive-nut to the other of said actuator ends; a casing having said electric motor mo...
