SQM56.564R1G3R Siemens Damper Motor

Overview

The Siemens SQM56.564R1G3R is a high-torque reversing actuator designed for the precise positioning of air and gas dampers, flow control valves, and other rotary applications in medium to large capacity oil and gas burners. Engineered for precision and repeatability, this electromotive motor is a critical component for load-dependent control systems, ensuring optimal combustion efficiency. It features a durable design capable of mounting in any position and is specifically configured for clockwise (CW) rotation.

Features

• High-precision modulating control with high rotational resolution and low hysteresis
• Internal auto/manual selector switch and manual forward/reverse toggle for easy adjustments
• Externally visible position indicator for quick status monitoring
• Includes two limit switches and four internal auxiliary switches that are easily adjustable
• Modular design with exchangeable circuit boards and potentiometers for field flexibility
• Disengagement clutches for the drive shaft and cam drum to facilitate manual setup
• Maintenance-free gearwheels and bearings for long-term reliability
