SQM53.467R1G3 Siemens Damper Motor

Overview

The Siemens SQM53.467R1G3 is a high-precision reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves. Part of the robust SQM5 series, this electromotive motor is engineered for industrial and commercial burner applications that require exceptional repeatability and modulating accuracy. It features a die-cast aluminum housing and a synchronous motor, providing reliable performance in demanding environments.

Features

• Internal and external position indication for easy monitoring
• Six internal, easily adjustable auxiliary switches for flexible control logic
• Auto/manual selector switch and forward/reverse toggle for simplified commissioning
• Disengageable drive shaft and camshaft via clutches for quick manual alignment
• High modulating accuracy with low hysteresis and potentiometer gearing
• Field-exchangeable circuit boards and shafts to accommodate various mounting needs

Specifications

• Torque: 200 lb-in (approx. 22.5 Nm)
• Running Time: 25 seconds for 90-degree rotation (at 60 Hz)
• Operating Voltage: 110V AC
• Control Input: Supports 4-20 mA, 0-10 VDC, 0-135 Ohm, and floating control
• Shaft Type: 14 mm round, single-ended shaft
• Rotation: Counterclockwise (CCW) when facing the driveshaft
• Protection Rating: IP54 (when used with appropriate cable glands)
• Operating Temperature: -4 F to 140 F (-20 C to 60 C)

Applications

• Load-dependent control of gas flow, oil volume, and combustion air in large burners
• Positioning of dampers in HVAC and industrial process heating systems
• Modulation of butterfly valves and flow control valves in combustion trains
• Use in dual-fuel applications where separate ignition and fire positions are required
• Integration into burner management systems, such as the Siemens LMV5 series
