Siemens Combustion SQM50.460R1G3 Motor

The Siemens Combustion SQM50.460R1G3 Motor is a high-precision reversing actuator specifically engineered for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves in industrial burner systems. Delivering a substantial 140 in-lb torque, this 110V damper motor is built into a rugged die-cast aluminum housing to withstand the thermal and mechanical rigors of boiler room environments. It operates with a 25-second run time for a 90-degree rotation and features 6 internal switches, including two limit and four auxiliary switches, which allow for complex control sequences such as high-fire, low-fire, and light-off positioning. Designed for high modulating accuracy, the unit utilizes a 4-20 mA input signal through an integrated circuit board and includes a 1000 Ohm potentiometer for precise position feedback. Technicians will appreciate the disengagement clutches for both the drive shaft and cam drum, facilitating rapid manual alignment during commissioning, alongside an auto/manual toggle switch for direct field control.

• Enhanced Control Versatility: Equipped with 6 adjustable internal switches to manage auxiliary equipment and multi-stage burner firing.
• Efficient Field Setup: Features a manual release button and forward/reverse toggle for easy linkage adjustment without power.
• High Repeatability: Engineered for 250,000 startup cycles, ensuring reliable performance in high-demand industrial process heating.
• Flexible Mounting: The NEMA 4 compatible design can be mounted in any orientation to accommodate tight burner configurations.
• Standardized Compatibility: Replaces common industrial actuators using AGA58 series shafts and standard mounting brackets.

What is the primary application for the SQM50.460R1G3?
This motor is primarily used in medium to large capacity oil and gas burners to control the volume of combustion air or fuel flow via rotary dampers and valves.

Does this unit include the drive shaft?
No, the shaft is not included. Depending on your linkage requirement, you will need to order a compatible AGA58 series shaft (such as the AGA58.1 or AGA58.4) separately.

Can the direction of rotation be changed in the field?
Yes. While this "R" suffix model is factory-configured for clockwise rotation (viewed from the gear end), it is field-reversible to suit specific installation requirements.
