System Integration and Operational Role
This motor typically mounts directly to a hydraulic amplifier or mechanical linkage. It receives its control signal from a primary unit like the Woodward 723PLUS digital governor. Furthermore, the integrated position feedback ensures closed-loop control for exceptional accuracy and repeatability in valve positioning.
Performance and Application
The servo’s high dynamic response allows for rapid adjustments to load changes. This capability is critical for maintaining grid frequency in power generation applications. Moreover, its rugged construction ensures longevity in high-vibration environments, much like how complementary protective devices such as the RMS-TSG-TZ-C Static Trip unit ensure electrical safety.
