SQM56.564R1Z3R Siemens Damper Motor

Overview

The Siemens SQM56.564R1Z3R is a high-precision reversing electromotive actuator designed to position air dampers and flow control valves in oil and gas burners of medium to large capacity. Engineered for precision and repeatability, this actuator is part of the SQM5 series and is specifically configured for clockwise (CW) rotation. It features a robust die-cast aluminum housing and a modular design that allows for significant field flexibility through exchangeable circuit boards and shafts.

Features

• High-precision synchronous motor with backlash-free gearing for accurate modulating control
• Modular design with field-exchangeable circuit boards to support various input signals and functions
• Includes six internal, easily adjustable switches (two limit switches and four auxiliary switches)
• Integrated auto/manual selector switch and manual forward/reverse toggle for easy adjustment and commissioning
• Externally visible shaft position indicator for rapid status monitoring
• Disengagement clutches for the drive shaft and cam drum to facilitate manual adjustments
• Maintenance-free gearwheels and bearings for a long service life of approximately 10 years or 250,000 startup cycles
