Description
WOODWARD
PART NO: 5484-877
PM MOTOR / SPEED SETTING ELECTRIC MOTOR
24 VDC 15 RPM
The Woodward 5484-877 is a permanent magnet (PM) electric motor rated at 24VDC with an output speed of 15RPM, designed for precision speed setting functions within marine control systems. As a low-speed, direct-drive actuator motor, it is typically employed to position governor controls, fuel racks, or throttle mechanisms where accurate and repeatable rotary movement is critical. In the marine environment, reliable speed setting directly influences engine response, load management, and operational safety — making the integrity of this component essential to the broader propulsion and power generation control architecture.
Key Features
✓ Permanent magnet DC motor delivering controlled rotary output at 15RPM on a 24VDC supply, providing consistent and repeatable positioning for speed setting duties.
✓ Rated at 24VDC with a nominal output speed of 15RPM; further electrical specifications such as current draw, torque rating, and shaft dimensions are subject to confirmation from nameplate data or Woodward documentation.
✓ Designed for integration with Woodward governor and control systems where an electric motor actuator is required to translate control signals into precise mechanical movement.
✓ Typically installed within enclosed control panels or governor housings in protected machinery spaces; mounting configuration and connector type should be verified against the specific installation drawing prior to fitment.
✓ As a direct replacement component within Woodward control assemblies, correct identification via part number and system model is recommended to ensure dimensional and electrical compatibility before installation.
Marine Applications
✓ Main engine and auxiliary engine governor systems requiring electric motor-driven speed setting on vessels operating variable load profiles.
✓ Diesel generator sets aboard cargo ships, tankers, and offshore support vessels where stable frequency and load sharing depend on precise governor actuation.
✓ Propulsion control systems on tugs, ferries, and workboats where responsive and accurate speed adjustment is operationally critical.
✓ Power management and load control panels on platform supply vessels and offshore installations utilising Woodward governing solutions.
✓ Retrofit and overhaul applications where an original Woodward PM actuator motor requires like-for-like replacement to restore governor system performance.
Why Marine Engineers Choose
Marine engineers specify Woodward components for their proven reliability in demanding shipboard environments, with a manufacturer reputation built on decades of precision governor and control system engineering. The 5484-877 motor offers a dependable like-for-like replacement that maintains the integrity of the original control system design without requiring recalibration of the wider governor assembly, subject to correct installation.
Ideal For
Cargo vessels, tankers, bulk carriers, offshore support vessels, platform supply vessels, tugs, ferries, and any commercial or industrial marine application utilising Woodward governor or speed control systems for main engines, auxiliary engines, or generator sets.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, compatibility assessment, installation guidance, and commissioning of this Woodward PM motor within existing control system configurations. Retrofit and integration support can be provided for vessels upgrading or overhauling Woodward governor assemblies, subject to confirmation of the specific system configuration. To confirm suitability and compatibility, buyers are encouraged to share nameplate photographs, the full part number, governor or control system model and version, relevant wiring or installation drawings, and vessel name or IMO number where applicable. All compatibility and application assessments are subject to confirmation based on the information provided.
