ABSTRACT:
An actuator assembly for moving a device between a retracted and extended position in which a ball screw is connected to the device and is in threaded engagement with a ball nut so that, upon rotation of the ball nut, the ball screw moves between a retracted and an extended position. A gear train is connectable between a power source and the ball nut for transferring torque therebetween to rotate the nut member, and a control system responds to a relatively low power input for selectively connecting the drive assembly between the power source and the ball nut member.
