Connect the multimeter across the terminals without disconnecting the motor leads.

For a delta connected motor, winding resistance = 1.5xmultimeter reading.

For a star connected motor with 3 leads brought out in the TB, winding resistance = 0.5xmultimeter reading.

For a star connected motor with 6 leads brought out in the TB, winding resistance = multimeter reading. (multimeter connected between phase and neutral)

star delta connection used in reduce the starting current at 3 times . how its reduce the current please explian .
