3 phase induction motor

The three phase induction motor is an alternating current motor

which is driven by the electromagnetic torque generated by the

Interaction between the rotating magnetic field formed by the

stater winding and the magnetic field of the induced current

in the rotor winding. it belongs to a kind of induction motor.

DOL starter, A DOL starter is 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.

How does DOL starter work? Principle of Direct On Line Starter DOL to start

The connection is closed applying full line voltage to the motor winding.

The motor will draw a very high inrush current for a very short time

magnetic field in the iron and then the current will be limited to the Locked

Rotor Current of the motor. why we use DOL starter? The applications of DOL starters are primarily motors where a high inrush current does not cause excessive voltage drop in the supply circuit or where this high voltage drop is acceptable. Direct on line starters are commonly used to start small water pumps, conveyor belts, fans and compressors.

what is the difference between dol and star delta starter. dol means the motor is connected directly ON Line using one contactor with no starting circuit to lower the high starting current. Typically the delta part of star delta. star delta uses two contactors, one to start at a lower voltage in star and one to run at a higher voltage in delta configuration.
