SQM56.560R1 Siemens Damper Motor

Overview

The Siemens SQM56.560R1 is a high-torque reversing actuator designed to provide precise rotary motion for industrial and commercial burner applications. As a base model in the SQM5 series, this electromotive actuator is engineered for the positioning of flow control valves, dampers, and butterfly valves in oil and gas burners of medium to large capacity. It is specifically built for applications requiring a high degree of modulating accuracy and repeatability. This particular version is a “base model” configuration, meaning it is typically supplied without a drive shaft, control board, or potentiometer, allowing for maximum customization in the field.

Features

• High-torque output of 310 lb-in (40 Nm) suitable for large dampers and valves
• Reversing motor design allows for both clockwise and counterclockwise operation
• Six easily accessible internal switches (2 limit and 4 auxiliary) for complex feedback and control
• Impact-proof and heat-resistant plastic covers with a durable die-cast aluminum housing
• Separate disengagement of drive shaft and camshaft for easy manual adjustment
• Externally visible position indicator for quick status monitoring
• Maintenance-free gear train with automatic re-engagement

Applications

• Load-dependent control of gas flow, oil volume, and combustion air volume in industrial burners
• Precise positioning of air and gas dampers in HVAC and boiler systems
• Operation of flow control valves and butterfly valves requiring high rotary torque
• Integration with 3-position or modulating controllers (e.g., 4-20 mA) via plug-in electronic modules
• Direct control by burner management systems in power generation or manufacturing plants
