Siemens Combustion SQM50.460R1H3 Motor
The Siemens Combustion SQM50.460R1H3 Motor is a high-precision reversing actuator designed for the exacting demands of industrial and commercial burner systems. Engineered for modulating control of gas and air dampers, this 110V unit delivers a robust 140 in-lb torque, ensuring reliable positioning of flow control valves and butterfly valves. The motor features a 25-second running time for a 90-degree stroke at 60Hz, providing the rotational speed necessary for responsive combustion air/fuel control. This specific SQM5 series damper motor is equipped with six adjustable auxiliary switches, including an internal economy position switch to ensure fully closed positioning when the burner is offline. Its 0 to 135 ohm input signal compatibility allows for seamless integration with legacy and modern 135-ohm proportioning controllers. Built for longevity in harsh mechanical rooms, it includes manual disengagement clutches for the drive shaft and cam drum, facilitating rapid commissioning and field alignment without specialized tools.
- Precision Modulation: Exceptional repeatability for precise fuel-to-air ratio adjustment in commercial boiler systems.
- High Torque Output: Rated at 140 lb-in torque to drive larger dampers and high-pressure flow valves without stalling.
- Integrated Auxiliary Switches: Includes 6 internal switches (2 limit, 4 auxiliary) for flexible sequence control and position feedback.
- Field Flexibility: Features an auto/manual selector and manual forward/reverse toggle for direct technician control during setup.
- Rugged Construction: UL and CSA-listed design optimized for thermal stability in high-heat combustion environments.
What are the primary applications for the Siemens SQM50.460R1H3?
Technicians typically utilize this actuator for positioning air and fuel dampers in medium to large capacity industrial gas burners. It is also frequently found in process heating applications requiring rotary motion for butterfly valves.
Is this actuator compatible with 4-20mA signals?
The R1H3 suffix specifically denotes a 135-ohm potentiometer input. For 4-20mA modulation, a different circuit board module or a specific 4-20mA variant (such as the R1G3) would be required, though the base Siemens SQM50 motor frame is similar.
How do I manually override the motor during commissioning?
The housing contains a dedicated auto/manual switch and a manual control toggle. Additionally, the shaft can be disengaged via the coupling pin to allow for manual alignment of the cam drum and drive shaft.
