What is the d/f between DOL & star delta starter & automatic star delta starter?..

Answer / basith

In a DOL starter motor terminals is directly connected to
starter such that initially a very high starting current is
feed to drive the motor.Dol starter is used for small
motors below 5hp because of high starting current may
damage motor winding. Dol starter using for large motor
using star delta connection,first motor run on star
connection mode upto 80% which provide low starting current
and low torque initally and after getting maximum torgue
motor operates on delta mode with high torgue.
