CONTROL MOTORS

In many industrial or commercial combustion installations the process temperature or pressure is controlled by an electronic instrument that senses temperature or pressure and relays to the burner the process heat input requirement.

The control instrument sends an electronic or electrical signal to the burner fuel input control equipment.

In many burner installations the control equipment comprises of a valve controlled by an electrical motor. The valves may be of the butterfly or ball type, and are generally connected to the control motor by means of a flexible, adjustable linkage.

Some ball type valves have the control motor fitted directly to the valve operator shaft.

Control motors normally use and operate with a 24v ac electrical supply, although motors that use 230v ac or 110v ac are available. Some motors are fitted with internal transformers to reduce the supply voltage down to the 24v ac required.

The conventional control method been to use a simple electrical balancing potentiometric system, although many modern burners are fitted with instrumentation that uses an electronic signal.

For more information regarding the design, structure and application of Control motors consult the Technical (controls) section of this web-site.
