all the above is not seems to be correct.. the real thing
is in star IL=Ip so we are going for star at the time of
starting. after the machine attains rated speed we are
changing into delta becuase the machine cannot develop
rated TORQUE of the motor in star but it can develop in
delta since in delta VL=VP. that's why its changed to delta
instead of running in star. V is directly proportional to
flux is inturn proportional to torque.
