摘要： Embodiments of an electric linear actuator may include a roller screw assembly, an electric motor coupled to the roller screw assembly, and a linear transducer operatively coupled with the roller screw assembly. The motor may be configured to drive the roller screw assembly to extend and retract another component, such as a rod. In some embodiments, the linear transducer may be configured to detect a position of the rod. The roller screw assembly may be coupled directly to the motor via a gear coupling, with the motor disposed generally in axial alignment with the roller screw assembly. Other embodiments disclosed herein include a veneer lathe carriage with electric linear actuators and corresponding apparatuses, methods, and systems.
