DYNA 8000 Series Rotary Actuators
DYNA 8000 / DYNA 8200 / DYNA 8400
Woodward DYNA 8000 Series rotary actuators are components of governor systems that provide engine governing for speed and power control of piston and gas turbine engines or steam and water turbines.
The DYNA hazardous duty actuators are UL listed for Class I, Division 2, Group D, hazardous duty applications often encountered in petroleum or chemical industries.
ACTUATOR
The actuator consists of an electromagnet with an iron armature rolling on the center shaft bearings, and has a return spring that balances the magnetic force of the armature. When DC current flows in the coil, the magnetic force moves the armature in the stator. This linear motion is transformed into rotary motion through a crank arm that forms part of the output shaft.
The all-electric, proportional actuators are compatible with all engines and can be mounted in any position on the engine.
Torque ranges for the 8000 Series actuators are:
- DYNA 8000: 1.4 N•m (1.0 lb-ft) with a 35° travel range
- DYNA 8200: 4.1 N•m (3.0 lb-ft) with a 45° travel range
- DYNA 8400: 7.3 N•m (5.4 lb-ft) with a 45° travel range
CONTROLLER
The electronic controller is the information processing unit of the governor assembly. It contains electronic components which process the input signal from the magnetic pickup that commands the engine to the desired speed/RPM set into the controller. Electronic adjustments are available on the controller for field adjusting the unit as necessary.
