SIEMENS servo motor SQM33.711A9

SIEMENS servo motor SQM33.711A9 SQM33.711A9 is a high-precision actuator specially designed for industrial burners. The core function is to achieve efficient combustion and low emission control by dynamically adjusting the damper opening or fuel valve. It belongs to the Siemens SQM33 series digital servo motor, adapted to LMV27 and LMV37 series combustion managers, and is commonly used for air-fuel ratio control of gas/fuel burners. Its design goal is to achieve high-precision adjustment through mechatronics while meeting reliability requirements in industrial environments. Torque and stroke: Running torque 10 Nm (holding torque 6 Nm), 90° rotation stroke time 17 seconds, support clockwise/counterclockwise bidirectional rotation, maximum rotation angle 160°. Protection Class: IP54 (IP40 at cable outlet), stable operation from -25°C to +60°C, resistant to vibration (IEC 60068-2-6) and electromagnetic interference (EN 61000-6-2). Electrical parameters: working voltage 24V±20%, power consumption 10W, supports analog control (2-10V or 4-20mA), and provides feedback signal output. Core functions: combustion process control, safety and protection mechanism, communication and scalability. Multi-section fire control: supports smooth two-section fire or proportional adjustment, and dynamically adjusts the output according to load needs (such as boiler steam pressure). Multi-fuel adaptation: The gas and fuel modes can be switched through software configuration, and are compatible with dual-purpose oil and gas burners. Operating temperature range: -25°C to +60°C, anti-vibration (IEC 60068-2-6) and electromagnetic interference (EN 61000-6-2), suitable for harsh environments such as boilers, hot air furnaces, smelting furnaces, etc.
