When selecting a burner servo motor (i.e., damper actuator/motor), key considerations include torque, running time, control method (proportional/segmented), and brand compatibility. This directly determines the accuracy of damper adjustment and combustion efficiency.
Core Selection Parameters
Torque: Determined by the size and resistance of the burner damper. Common specifications are 2Nm, 3Nm, and 5Nm; large industrial burners may require 10Nm or more. Insufficient torque will not be able to drive the damper, while excessive torque may damage the mechanical structure.
Running Time: Refers to the time required for the servo motor to rotate 90° (e.g., 4.5 seconds, 12 seconds, 30 seconds, etc.). It needs to be matched to the response speed requirements of the combustion control system.
Control Signal:
On/Off (Two-stage): Only fully open, fully closed, or high/low flame states are available.
Proportional Adjustment: Receives 4~20mA or 0~10V signals from a combustion program controller (such as a proportional controller) to achieve continuous stepless adjustment of the damper angle.
Rotation Angle: Most burner dampers rotate at 90° or 160°.
Common Mainstream Brands and Models
Siemens: One of the most commonly used brands of industrial burners. Examples include the SQN3 series (low power), SQN7 series (medium power), and SQM5 series (high power, high torque, and high precision).
Honeywell: Commonly used in various commercial and industrial burners, offering high reliability and a wide range of feedback options.
Langier/Girard: Very common among European and American burner brands, often used as original equipment manufacturer (OEM) parts.
Selection Considerations
Replacement Principle: When replacing an old unit, it is best to strictly match it according to the brand, model, and voltage (commonly 220V or 24V) of the original servo motor.
Axial and Flange: Confirm the shape of the motor's output shaft (e.g., D-type shaft) and the flange mounting hole positions to ensure a perfect fit with the fan damper mechanical structure.
Feedback Potentiometer: If the servo motor needs to provide position signals to the combustion controller, be sure to confirm the resistance value of the built-in potentiometer (e.g., 1000 Ω, 2000 Ω, or 5000 Ω).
