Woodward 8235-650 ProAct Plus Industrial Actuator LAT

Overview

The 8235-650 industrial actuator from Woodward is a precision electromechanical positioning device developed for closed-loop control of engine fuel and air systems. As a member of the ProAct / ProAct Plus actuator platform, it incorporates Limited Angle Torque (LAT) motor technology to achieve fast, repeatable output movement with high holding force.

Designed for direct mechanical coupling to fuel racks or throttle levers, this actuator operates as the final control element within electronically governed engine systems. It is widely deployed in stationary and mobile power generation applications where stable speed regulation and rapid load response are required.

Technical Characteristics

The 8235-650 actuator integrates power electronics and position feedback into a compact, sealed housing, minimizing external components and simplifying system wiring.

Key performance attributes include high torque density, short response time, and precise angular positioning over a limited travel range. The LAT motor design eliminates continuous rotation, improving reliability and reducing wear compared with conventional servo motors.
