L-Series Linear Actuators

Ultra Motion's L-Series of advanced linear servo actuators utilizes robust mechanical elements and state-of-the-art materials and components to deliver excellent performance and high torque for dynamic drone and robotics applications. Featuring integrated brushless DC control electronics and contactless absolute position feedback, they are highly reliable even under the most demanding of conditions.

The compact and versatile actuators are ideal for dual redundant UAV system designs, incorporating redundant motors, control electronics, and a triplicated absolute position sensor with 100% electrical isolation. The redundant actuator can be used in a cold-standby or load sharing arrangement, and position and phase currents can be completely controlled via CAN 2.0B or RS-485 serial communication protocols.
