Abstract
An actuator having an electric motor with a rotor shaft engaged with a gear set within a housing is provided. As an example, the gear set may be a planetary gear set. The planetary gears are engaged with a disk. The disk is fixed to a shaft rod or other force transmitting component such as lead screw. The lead screw is engaged with a traveling block. When the load screw rotates, the traveling block moves along the lead screw. The lateral movement of the traveling block may be linked to further force application devices, such as a pin or a cable. In one embodiment, the rotor shaft is a hollow tube, and the lead screw is a spindle or rod disposed to slide in and out of the rotor shaft tube.
