Application Areas

• Diesel engine speed governor systems
• Generator sets (genset control systems)
• Marine propulsion systems
• Industrial prime movers
• Oil & gas auxiliary engines
• Power plant auxiliary control systems

System Role (Important)

This motor is typically used inside a Woodward mechanical/electro-hydraulic governor system, where it:

• Adjusts fuel rack or control linkage
• Maintains constant engine speed under load changes
• Works with governor control logic or actuator system
• Provides precise mechanical positioning feedback control

Advantages

• High reliability for continuous industrial operation
• Precise low-speed control (stable governor response)
• Strong torque output at low RPM
• Proven use in marine and generator systems worldwide
• Durable construction for vibration and harsh environments

Precautions

• Must be installed in compatible Woodward governor system
• Do not apply incorrect voltage (24VDC only)
• Ensure proper mechanical alignment with linkage system
• Avoid dry running without load connection
• Check gearbox condition if integrated in assembly
