A 3-phase delta-connected squirrel cage induction motor when started with a DOL starter has a starting torque of 600 NM. Its starting torque when star-delta starter is used:

### Right Answer is: 200 NM

#### SOLUTION

Starting torque of the star delta starter is equal to 1/3 of its delta value

Hence starting torque = 600/3 = 200 NM
