Wiring Diagram Of Direct On Line Starting Of Three Phase Induction Motor. A direct on line starter or dol starter is used to start the 3 phase induction motor through connecting the three phase supply to motor stator winding. All other control and power connections have to be made by the installer.
An induction motor is similar to a poly phase transformer whose secondary is short circuited. Direct on line dol starter full voltage starting reduced voltage starting. A2 14 18.
