5464-335 WOODWARD

Each Woodward Electrically Powered Governor (EPG) system includes three 

basic parts: 

· A magnetic pickup (MPU) which senses engine speed from an enginedriven gear. 

· A speed control which receives the speed signal from the MPU, compares it 

to a reference signal, and generates a control signal which the control sends 

to the actuator. 

· An actuator which receives the signal from the control and positions its 

output shaft according to this signal. The output shaft is linked to the fuel 

control. 

There are two EPG models: 

· The isochronous speed control, which is available with start-fuel limit or dual 

dynamics; 

· The droop speed control, which includes a load sensor and provides droop 

control for generator sets. 

Different actuator sizes are available for different work output requirements. 

Models are available for either 12 or 24 volt systems.
