SQM56.567R1A3R Siemens Damper Motor

Overview

The Siemens SQM56.567R1A3R is a high-precision reversing actuator designed to position air and gas dampers, flow control valves, and butterfly valves in industrial and commercial burner systems. Engineered for reliability and accuracy, this electromotive motor is particularly well-suited for applications requiring a high degree of modulating accuracy and repeatability. It features a robust design with a die-cast aluminum housing and a synchronous motor capable of delivering significant torque for large-scale combustion systems.

Features

• Self-checking mechanism with an integrated auto/manual selector switch for easy adjustments and commissioning
• Equipped with six internal, easily adjustable auxiliary switches for flexible position feedback and control
• Low hysteresis gear train with double-offset drive ensures precise positioning and rotational resolution
• Field-reversible clockwise (CW) rotation when facing the gear end, as indicated by the “R” suffix
• Durable construction with an impact-proof and heat-resistant plastic cover and die-cast aluminum housing sections
• Integrated 1000 Ohm, 90-degree potentiometer for accurate position feedback to the burner control system
