They are compact motors, with a built in gear set. They are used to control butterfly or similar type restrictors. Damper motors are extremely common in HVAC applications. On burners they are frequently used to modulate the air or gas flow, allowing for better control and increasing the flexibility of the burner, whilst increasing efficiency by saving any otherwise wasted fuel.
When selecting a Damper motor (Servo Motor) there are quite a number of variables to check. These include the torque output of the motor, usually measured in NM (Newton Meters), the type of output, either a hollow bore, or a shaft with a keyway or a flat. Other variables include the rotation direction, and also the maximum degrees of rotation.
We list the most common servo or damper motors here on our web shop, but we have access top the full range of Siemens Damper Motors and Econex Servo Motors so if you cannot find the one you are looking for, just call us or email, and we will get the lead time and send you a quote.
