Woodward 3522-1004 EM-Driver for EM-80 / EM-300 Actuators
Product Type: All-electric servo driver for EM series fuel actuators Part Number: 3522-1004 Compatible Actuators: EM-80, EM-300 brushless electric actuators System Overview: This EM-Driver works together with EM-80 or EM-300 actuator to realise fuel valve position regulation for gas engines, diesel engines and turbines. The actuator adopts three-phase brushless AC motor plus precision planetary gearbox, resolver for closed-loop position feedback. Same mounting footprint for EM-80 and EM-300 for interchangeability.
Actuator Travel: 40 degrees maximum output rotation EM-80 Performance: Continuous nominal torque 91 N·m, peak transient torque 190 N·m for 1 second, single-stage planetary gear ratio 1:7 EM-300 Performance: Continuous nominal torque 260 N·m, peak transient torque 429 N·m for 1 second, two-stage planetary gear ratio 1:20 Slew Time: Approximately 192 ms (10% to 90% stroke, no-load for EM-300) Output Flange: ISO 9409 standard flange, fitted with mechanical breakaway stops and local position indicator pointer
Driver Power Supply: 3-phase 400 Vac to 480 Vac, 50 / 60 Hz, tolerance ±10% Control Command Input: 4–20 mA analog setpoint signal Feedback Signal: Resolver position sensing; driver provides isolated 4–20 mA position feedback output (4 mA = 0%, 20 mA = 100%) Digital Communication: RS485 interface with proprietary Woodward protocol, supports connection to MicroNet and NetCon control systems, for command, feedback, alarm and fault reset Internal Diagnostics: Motor fault, resolver fault, overcurrent, overvoltage, overtemperature, travel limit alarm, event logging EMI Protection: Equipped with built-in power filter to suppress electromagnetic interference
Actuator Operating Ambient Temperature: 0 °C to +85 °C, continuous torque derating above 40 °C Driver Installation: Cabinet mounting, IP20 protection rating Mechanical Feature: Low-backlash high-stiffness gear train, no carbon brushes, long service life Certifications: CE marked, optional marine certifications including ABS, BV, DNV Commissioning Tool: Windows PC configuration software for parameter setup, stroke calibration and diagnostic testing
Typical Applications: Gas generator sets, reciprocating gas compressors, marine prime movers, industrial turbine fuel control systems Functional Notes: One EM-Driver model supports both EM-80 and EM-300; only software configuration needs to be adjusted for different actuator variants
