Dol starter control circuit diagram explanation. Easy way dol starter circuit and control diagram dol direct on line self teach bd. When we push stop button control circuit of starter will be break at stop button and supply of relay coil is broken plunger moves and close contact of main contactor becomes open supply of motor is disconnected. The wiring of direct on line control circuit starter is following. Dol starter control diagram.

The starting current is not so very high and these motors can withstand starting current without any starters. The circuit breaker is used for protection against short circuits while the overload relay protects the motor from overloading. In this post we are going to know the details of each part of dol starter diagram all parts of the dol starter power circuit diagram and control circuit diagram are explained direct online starter or dol starter is very useful and commonly used ac starter dol starters are mainly used with up to 5 h p motors. The connection of contactor can be done among relay coil supply voltage as well as thermal overload.

Thus there is no need to reduce the applied voltage to control the starting current. The contactor is used for starting and stopping the motor where the green and red buttons are connected. A dol starter or direct on line starter or across the line starter is a method of starting of a 3 phase induction motor in dol starter an induction motor is connected directly across its 3 phase supply and the dol starter applies the full line voltage to the motor terminals. The dol starter is made of a circuit breaker or mccb or fuse an overload relay and contactor or coil.

What is dol starter. In this article you will learn about dol direct on line starter control diagram. Dol wiring scheme motor starting characteristics on dol starter. In this article we will discuss dol starter direct online starter working principle and construction dol starter diagram control diagram power circuit and wiring single 3 phase starter direct on line is the simplest and cheapest method used for starting three phase motor.

Despite this direct connection no harm is done to the motor.
