SQM56.560R1A Siemens Damper Motor

Overview

The Siemens SQM56.560R1A is a high-torque, reversing electromotive actuator designed to drive air and gas dampers in medium to large capacity oil and gas burners. Engineered for precision and repeatability, it is particularly well-suited for industrial and commercial applications requiring accurate modulating control. This base model is designed for flexibility, featuring a modular construction that allows for the addition of various electronic modules and shaft designs to meet specific system requirements.

Features

• High-torque output of 310 in-lbs for demanding industrial damper and valve applications
• Internal auxiliary switches (six) provide flexible feedback and control options
• Reversible synchronous motor allows for clockwise and counter-clockwise operation
• Disengagement clutches for both the drive shaft and camshaft enable manual adjustments
• Integrated auto/manual switch and manual forward/reverse toggle for easy commissioning
• Rugged design with die-cast aluminum housing and impact-resistant plastic covers
• Externally visible position indicator for quick status verification
