SQM50.460R1 Siemens Damper Motor

Overview

The Siemens SQM50.460R1 is a high-precision reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves. As a base model in the SQM5 series, this electromotive actuator is engineered for medium to large capacity oil and gas burners. It is specifically designed to handle applications requiring a high degree of modulating accuracy and repeatability. This particular configuration is a base unit that does not include a shaft, control board, or potentiometer, allowing for maximum field customization and flexibility in industrial and commercial burner systems.

Features

• Reversible and locking-proof synchronous motor ensures reliable operation under various loads
• Separately adjustable driven shaft and cam shaft for precise mechanical alignment independent of the gear train
• Manual disengagement of the shaft from the gear and motor via a coupling pin for easy setup and maintenance
• Die-cast aluminum housing sections and impact-proof, heat-resistant plastic covers for durability in harsh environments
• Internal and external position indication through viewing windows and internal scales
• Maintenance-free gearwheels and bearings reduce long-term operational costs
• High torque capacity of 140 in-lbs for demanding industrial damper applications
