Answer / msivakailash85

if motor connected in star then high torque and power
if motor connected in delta then low starting current(cable
size also less)

Answer / pillay

There is no advantage.If the motor is designed to operate at
star connection than you must operate as such. like wise
if it is designed to operate on delta connection then
you must connect in delta.If the motor is operated with
