Woodward 8200-224 Servo Position Controller

GENERAL INFORMATION

The DYNA 8000, DYNA 8200 and DYNA 8400 governor system provides an engine governor for speed and power control of piston and gas turbine engines or steam and water turbines.

The actuator is a simple, proportional, electric solenoid having a sliding armature whose magnetic force is proportional to input coil current. The armature glides on anti-friction bearings and is balanced between the force of its return spring and the magnetic force, thus providing a hysteresis-free linear movement. The linear motion is converted to an output shaft rotation by a crank arm.

FUNCTIONAL DESCRIPTION

The actuator consists of an electro-magnet with an iron armature rolling on the center shaft bearings. The actuator is provided with a return spring which balances the magnetic force of the armature. When DC current flows in the coil, the magnetic force tends to move the armature in the stator and this linear motion is transformed into rotary motion through a crank arm that forms part of the output shaft.
