8290-184 Woodward Electrically Powered Governor


Woodward electrically powered governor P.N. 8290-184

The EPG is designed for precise speed control of diesel, gas, gasoline engines, and gas turbines. The governoris especially suited to prime movers without a mechanical drive or hydraulic oilsupply for the governor andwhich have low-mass, low-friction fuel linkages.Controls are built with dynamics designed for specific engine applications.Units with start fuel limit canprevent startup overspeed and excessive startup smoke. The start fuel limit is automatically removed whenthe engine nears selected speed.The EPG is compatible witha full line of Woodward accessories providing for various levels of precisioncontrol of electrical generation or other processes.An EPG system with position feedback from the actuator provides start-fuel limiting, actuator compensation,droop, and added stiffness.

Actuator Specifications:

  • Output Shaft:0.375″-36 SAE serrated shaft on each end
  • Ambient Temperature Range: –40 to +93 °C (–40 to +200 °F)
  • Mounting: Mount in any configuration. The installation must not require lengths ofwiring greater than those specified in the Maximum Wire Length chart.
  • Construction: Aluminum and steel parts. All parts treated for corrosion resistance. Notpainted.
  • Work Output:Internal return springs provide operating force in the decrease-fuel direction. Additional, external spring must not be used.
  • Vibration: US MIL-STD-810C, method 514.2, procedure I, curve J per figure 514.2-2except limited to 3 g.
  • Shock: US MIL-STD-810C, method 516.2, procedure I, figure 516.2-1, GroundEquipment test, 40 ginput, 11 ms duration. A total of 18 terminal peaksawtooth shock pulses applied by the shaker machine, 6 in each axis, 3 ineach direction (plus and minus).

Product Specifications:

  • 12 Volt Supply: 12 Vdc (10 Vdc minimum to 16 Vdc maximum) 60 W maximum powerconsumption. A battery charger must be capable of at least 7 A when thegovernor is energized.
  • 24 Volt Control: 24 Vdc (20 Vdc minimum to 32 Vdc maximum) 95 W maximum powerconsumption. A battery charger must be capable of a least 5 A when thegovernor is energized.
  • Fuse and Wiring:A 10 A slow-blow fuse or circuit breaker must be installed in the nongroundedbattery lead. Route the battery leads directly to the speed control,not through any distribution points.
  • Magnetic Pickup: Must provide 1.5 Vrms minimum and typically 100 Hz while cranking.
  • Stability and Gain:These adjustments set the speed control’sresponse to match theindividualprime mover characteristics. Slow and fast response settings are providedwith the dual-dynamics controller.
  • Rated Speed: A 25-turn internal potentiometer sets rated speed.
  • Idle Speed: A 50KApotentiometer can be connected to set the idle speed between 25%and 100% of rated.
  • Steady State Speed Band:The control typically maintains ±1/4 of 1% of rated speed.
  • Ambient Temperature Range: –40 to +75 °C (–40 to +167 °F)
  • Mounting:Engine skid mountable in any attitude. The installation must not requirelengths of wiring greater than those specified in the Maximum Wire Lengthchart.
  • Speed Trim (Optional):A potentiometer can be connected to trim rated speed. Use a 1kWpotentiometer for a ±2.5% speed change. Use a 2 kW potentiometer for a±5% speed change.
  • Ramp Time, Idle/Rated (Optional):Install a capacitor to add up to four seconds ofacceleration and decelerationcontrol. Use a Ramp Generator for longer times.
  • Start Fuel Limit: Start Fuel Limit is adjustedwith an internal 10-turn potentiometer. Thelimitsets the maximum terminal shaft position until 95% of the selected (idle orrated) speed is attained. Start Fuel Limit is re-established when themagnetic pickup frequency drops to 5% of rated speed or lower.
  • Construction: The control box is constructed of cast aluminum and weighs about 0.5 kg (1lb).
  • Agency Qualified:EMC directive 89/336 EEC. Complies with EN50081-1, EN 50082-2.
