Reverse Forward DOL Starter Power and control Wiring

How does a DOL starter work?
The simplest form of motor starter for the induction motor is the Direct On Line starter. The Direct On Line Motor Starter (DOL) consist a MCCB or Circuit Breaker, Contactor and an overload relay for protection. Electromagnetic contactor which can be opened by the thermal overload relay under fault conditions.

What is meant by DOL starter?
A direct on line (DOL) or across the line starter applies the full line voltage to the motor terminals, the starters or cubicle locations, can usually be found on an ELO drawing. This is the simplest type of motor starter. A DOL motor starter also contains protection devices, and in some cases, condition monitoring.
What is DOL and RDOL?
RDOL Starter consists of two contactors connecting power supply to the Motor. The two contactors are complimentary to each other and can be used to reverse the direction of motor. As supply is connected directly to the motor it is named as Reverse DOL Starter.

How does a star delta motor starter work?
Working Principle of Star-Delta Starter. This is the reduced voltage starting method. The Star/Delta starter is manufactured from

two contactor interlocking.
easy way magnetic contactor interlocking diagram connection.
Magnetic contactor are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from on and off state. magnetic contactor act as a safeguard to protect the power supply and the motor.
why interlocking is used for the contactors?
A technique called interlocking is used to prevent the contactors from being energized simultaneously or closing together and causing a short circuit. this interlock locks out one contactor at the beginning of the stroke of either contactor to prevent short circuits and burnouts.
