SQM56.564R1G3 Siemens Damper Motor

Overview

The Siemens SQM56.564R1G3 is a high-torque reversing actuator designed for the precise positioning of dampers, flow control valves, butterfly valves, or any industrial application requiring controlled rotary motion. Engineered for accuracy and repeatability, this electromotive actuator is a critical component in industrial combustion systems and large-scale HVAC operations. It features a rugged die-cast aluminum housing and impact-resistant plastic covers, ensuring durability in demanding environments. The unit provides highly modulating accuracy and low hysteresis, making it ideal for systems that require fine-tuned airflow or fuel-to-air ratio management.

Features

• High-torque performance suitable for controlling very large dampers and valves
• Reversing motor allows for both clockwise and counter-clockwise rotation (field reversible)
• Integrated auto/manual switch and manual control toggle for easy setup and field adjustments
• Externally visible shaft position indicator for quick visual status checks
• Self-locking gear train ensures the shaft remains in position when power is removed or interrupted
• Field-exchangeable circuit boards and potentiometers for versatile control options
• Maintenance-free gearwheels and bearings for long-term operational reliability
• Internal and external position indication for precise feedback and monitoring
