The control circuit. In this post we are going to know the details of each part of dol starter diagramall parts of the dol starter power circuit diagram and control circuit diagram are explaineddirect online starter or dol starter is very useful and commonly used ac starterdol starters are mainly used with up to 5 hp motors.
Start Stop Jog Circuit Motor Control Circuit Diagram
Dol control circuit diagram. Direct on line starter wiring diagram. The contact are connected directly in the control circuit of dol to switch on km1 contactor. In three phase dol starter wiring the two types of wiring done. The control circuit and the power circuit. The connection of contactor can be done among relay coil supply voltage as well as thermal overload. The l1 contactor is connected from normally open no to r phase using mccb.
How dol starter control diagram works when we press the start button to start the motor the relay gets the phase and circuit completed thus coil energizes and contactors produce magnetic field the main contactor closes and motor gets the supply and the motor startswhen we press the stop button the circuit will interrupt and the motor stop. It is powered by only 2 phases of the power supply and it is responsible for starting and stopping the power supplied to the motor. And nc off switch and no on switch. Three phase dol starter wiring diagram for 3 phase motor. There are two types of circuits in the dol starter diagram given above. The wiring of direct on line control circuit starter is following.
Wiring diagram of dol starter. Can you please explain this phenomenon or the reasoning of this problem. Dol starter control diagram three phase. In the diagram you will see the three pole mccb circuit breaker molded case circuit breaker a magnetic contactor a motor over current thermal overload protection relay.
