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.
