DOL is used to start electric motors.
Many types of electric motor starter is available.DOL is one of the simplest starter. It is composed of electrical circuit and electro-mechanical parts to start and stop an electric motor.
A DOL starter connects the motor terminals directly to the power supply. Hence the motor is subjected to the full voltage of power supply. Consequently,higher starting current flows through motor.
DOL starter is suitable for small motors below 5 hp.
The control circuit is typically run at 220v or 100v or 24 v with the aid transformer.
