Common Motor Control Circuits Text Symbols

When you come into contact with different motor circuits, you will find that some motor control circuits are very simple and some are very complex, but in fact the basic control circuit is universal, the difference lies in what equipment the motor drives.

1.  If it drives a fan, it is called a fan control circuit; 
2.  If it drives a water pump, it is called a water pump control circuit; 
3.  If it drives a concrete mixer, it is called a mixer control circuit; 
4.  If it drives a boiler induced draft fan, it is called a control circuit. It is the control circuit for the induced draft fan of the boiler. 

The motor control circuit is flexibly designed according to the production process and the actual needs of the site.

The text symbols of the commonly used switchgear in the circuit diagrams of this site are introduced, as shown in Table 1-1.
