WOODWARD BUM60-1224-54-B-001-VC-A0-0093-0013-G003-0000 3522-1004 Motor drive and control components
The Woodward BUM60 (manufactured under the Baumüller partnership) and the 3522-1004 represent a sophisticated motor drive and control assembly.
1 Specifically, the BUM60 is a high-performance modular servo drive often integrated into Woodward’s turbine or engine control systems to provide precise electronic actuation for fuel valves or steam racks.2
Introduction
The BUM60-1224… is a “back-of-panel” modular servo inverter, while the 3522-1004 is often the associated control module or firmware-specific hardware designation.
Together, they form a closed-loop system capable of controlling synchronous or asynchronous motors with high dynamic response.
This specific configuration (indicated by the long alphanumeric string) defines the power stage, control type (VC – Vector Control), and specialized cooling or communication options.
