Woodward EM-80/EM-300 Electric Actuator Specification Guide

The Woodward EM-80/EM-300 MDS 5150A/LIT Actuator System provides a robust, all-electric solution for the control of large prime movers. By offering two distinct models, Woodward caters to the diverse needs of the industry: the EM-80 for applications demanding high-speed response and the EM-300 for those requiring high torque output. Both systems share a common architecture of a brushless AC motor, precision planetary gearbox, and a programmable digital driver, ensuring reliability and precision.
Compliance with major maritime classification societies (ABS, BV, LR, RMRS) and rigorous environmental testing (shock, vibration, humidity) makes these actuators suitable for the harshest environments found on ships and offshore platforms. The elimination of hydraulic oil not only simplifies the maintenance schedule but also eliminates a significant environmental hazard. Whether applied to a large diesel generator set or a steam turbine governor, the EM-80/EM-300 series stands as a cost-effective, high-performance solution for modern rotary actuation needs.
