Answer / mrt

we can start the motor either in star ot delta. in star
line current is equal to phase current and the line voltage
is 1.732 times the phase voltage . so the appplied voltage
is low so the magnetic field is low and motor runs in lower
speed with more current.

Answer / mahavir jagdev

with the lower voltage being applied to the stator winding it will keep on running at slow speed.

Answer / rajib

As the applied voltage is 1/1.732 times, so the torque
produced is less, so less output is there.

In three phase supply why we use R Y B Colour not other.
