SIEMENS servo motor SQM33.511A9

Product Model:

SIEMENS servo motor SQM33.511A9 The SQM33.511A9 is a core component designed for burner control systems, mainly used to precisely adjust damper opening or fuel valves for efficient combustion and low emissions, adapted to LMV27 and LMV37 series combustion managers, 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. Protection level is: IP54. Drive mode: Use a synchronous motor with self-locking, with a running torque of 3Nm and a holding torque of 2.6Nm, supports clockwise/counterclockwise bidirectional rotation, and the maximum rotation angle is 160°. Electrical parameters: Operating voltage is 24V±20%, power consumption is 10W, can be controlled by analog signal (2-10V or 4-20mA), and feedback signal output is provided. Operating temperature range is -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. 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.
