SQM56.564R1A3 Siemens Damper Motor

Overview

The Siemens SQM56.564R1A3 is a high-precision electromotive reversing actuator designed to position air dampers and flow control valves in medium to large capacity oil and gas burners. Engineered for industrial combustion systems, this robust damper motor provides reliable, load-dependent control of combustion air, gas, or oil volumes. Its modular design features a die-cast aluminum housing and impact-resistant plastic covers, ensuring durability in demanding thermal environments.

Features

• High-torque performance delivering up to 310 in-lbs for large damper applications
• Reversible synchronous motor protected against locking
• Equipped with six internal, easily adjustable switches for precise limit and auxiliary control
• Integrated auto/manual toggle switch and externally visible shaft position indicator for simplified setup
• Disengageable drive shaft and camshaft for easy manual adjustment
• Low hysteresis gear train combined with a 1000 Ohm potentiometer for superior modulating accuracy
• Support for multiple exchangeable circuit boards to accommodate various control signals and functional requirements
