ABSTRACT:
Disclosed is an electrically operated linear actuator which is modular in design such that each module provides a component of force required to cause translational motion to a load via a linear shaft. The actuator is designed so that all modules of the actuator are utilized to provide a maximum force for initial movement of the shaft, whereas only the last module is utilized to provide a minimum force when the shaft has completed most of its translational motion. Intermediate modules between the first and last modules provide components of force for translating the shaft that vary in a uniformly ascending order from the minimum to the maximum forces.
