The L2D Linear Servo Actuator is a dual-redundant linear actuator for safety-critical designs. The L2D is a dual redundant linear servo actuator that has been engineered to provide single electrical fault tolerance for safety-critical airborne system designs. While maintaining high performance under the most challenging of conditions, it includes state-of-the-art materials and components, integrated BLDC control electronics, and proprietary contactless absolute position feedback technology. The robust IP67-rated
actuator incorporates redundant motors, control electronics, and a triplicated absolute position sensor for voting. Control of redundant operation is handled entirely by the user with no arbitration, voting, or redundancy decisions made by the actuator, and the host can use the redundant actuator in either a cold-standby or load-sharing arrangement. The redundant controllers and triplicated sensor are 100% electrically isolated, and an optically-isolated enable input is provided as a hardware disable that removes power from the motor bridge when inactive, bypassing the onboard control electronics completely. Actuator position and phase currents can be controlled via CAN 2.0B and RS-485, and detailed health and state information can be obtained.
