Single phase dol starter wiring diagram. Figure 6 shows a typical dol starter with overcurrent and overload protections.
Direct Online Starter Dol Starter Wiring Diagram Diagram Electronic Engineering Motor
In the above three phase dol starter wiring diagram.
3 phase dol starter wiring diagram pdf. The r y b is the three phase 380 volts supply. In a 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. It comprises an enclosure in steel or plastic a contactor start contact link wires and stop start buttons.
Wiring of the direct on line dol motor starter 1 three phase supply 230volt coil see wiring diagram. Dol starter wiring diagram for three phase motor to wire a 3 phase motor the first thing to wire is a circuit breaker which is a disconnect and connecting point then we will get the supply from the circuit breaker and connect the supply to the contactor or starter and then to the overload relay. And the normally open and normally close push button shown.
Wiring of the direct on line dol motor starter 1 three phase supply 230volt coil see wiring diagram. Dol starter wiring diagram 3 phase pdf connecting a small electrical motor to a power source via a switch or by plugging induction motor directly to the power source via a three phase contactor. 1 2 2kw motor with a flc of 5 amps 415volts.
The direct on line motor starter dol is designed to switch a single or three phase induction motor at rated voltage. The coil of the contactor is 380 vac. We have to use all 3 poles of the overload relay otherwise the imbalance due to the current flow in only 2 of them will cause unnecessary tripping.
To use three phase electricity a motor needs windings spaced 120 degrees apart. A dol starter also known as a direct on line starter or across the line starter is a method of starting a 3 phase induction motor.
