SQM53.464R1Z3 Siemens Damper Motor

Overview

The Siemens SQM53.464R1Z3 is a high-precision reversing damper motor designed to drive air and gas dampers in medium to large capacity oil and gas burners. Engineered for load-dependent control of fuel and combustion air volumes, this electromotive actuator offers exceptional modulating accuracy and repeatability. It features a robust industrial gear mechanism and a reversible, locking-proof synchronous motor housed in a durable die-cast aluminum casing with impact-proof covers. The SQM53.464R1Z3 is a multi-input model, allowing it to accommodate various control signals, making it highly adaptable for complex industrial combustion systems.

Features

• Reversible synchronous motor provides reliable and precise rotary motion
• Adjustable driven shaft and camshaft via two separate, independent couplers
• Integrated electronic module supports multiple input signals including 4 to 20mA, 0 to 135 Ohm, and 0 to 10 VDC
• Disengagement clutches for both the drive shaft and cam drum to facilitate manual adjustment
• Internal and external position indication for real-time monitoring
• Equipped with up to eight internal switches (two limit and six auxiliary) for flexible control logic
• Flexible mounting options and field-exchangeable shafts to simplify replacement of competitive actuators
• UL recognized and CSA certified for use in North American industrial environments
