Dol Starter Drawing. Since the dol starter connects the motor directly to the main supply line the motor draws a very high inrush current compared to the full load current of the motor up to 5 8 times higher. Dol starter basically comprises of only two buttons one of them is green and other is red green button is used for starting and red button is used for stopping the motor.
The value of this large current decreases as the motor reaches its rated speed. And the normally open and normally close push button shown. Direct on line starter dol starter bill of material starter control and power wiring drawing details of control and power wiring with ferul numbering.
In the above dol starter diagram.
The dol starter cannot reduce the voltage or current during starting of the motor like other starters. The dol starter cannot reduce the voltage or current during starting of the motor like other starters. When the motor draws overcurrent the thermal overcurrent relay will trip the circuit and the motor disconnect from the supply. Since the dol starter connects the motor directly to the main supply line the motor draws a very high inrush current compared to the full load current of the motor up to 5 8 times higher.
